Temporal is a microservice orchestration platform which enables developers to build scalable applications

Last update: Jan 1, 2023

Overview

Temporal

Temporal is a microservice orchestration platform which enables developers to build scalable applications without sacrificing productivity or reliability. Temporal server executes units of application logic, Workflows, in a resilient manner that automatically handles intermittent failures, and retries failed operations.

Temporal is a mature technology, a fork of Uber's Cadence. Temporal is being developed by Temporal Technologies, a startup by the creators of Cadence.

Learn more about Temporal at docs.temporal.io.

Getting Started

Download and Start Temporal Server Locally

Execute the following commands to start a pre-built image along with all the dependencies.

git clone https://github.com/temporalio/docker-compose.git
cd docker-compose
docker-compose up

Refer to Temporal docker-compose repo for more advanced options.

Run the Samples

Clone or download samples for Go or Java and run them with the local Temporal server. We have a number of HelloWorld type scenarios available, as well as more advanced ones. Note that the sets of samples are currently different between Go and Java.

Use CLI

Use Temporal's command line tool tctl to interact with the local Temporal server.

alias tctl="docker exec temporal-admin-tools tctl"

add address translation to Cassandra persistence

What changed?

This PR adds the possibility to specify so called address translator for Cassandra nodes. Address translation is well-known feature in Datastax Java driver as well as in gocql driver.

Address translation is used in case the client can not resolve the IP addresses which Cassandra gocql driver returns. This happens in case when, for example, Cassandra nodes are running behind some kind of a proxy or load balancer so internal IP addresses do not make sense to the client side. Address translator solves this so the addresses are meaningful.

In Temporal context, we need to run Cassandra nodes in Amazon PrivateLink setup. This is very much deployment specific but the basic idea is that you have a running Cassandra cluster in one VPC and temporal server in the other and you are connecting to Cassandra via exposed, so called Endpoint and Endpoint service. This is very handy deployment model for businesses which would like to have their Temporal server in their vpc / account and they would like to just use Cassandra cluster as a service which is possibly deployed by 3rd entity.

WARNING: I have fixed the address translation in upstream gocql repository in this commit (1) for Cassandra 4.x nodes. For Cassandra 3.x nodes, the port will be static - 9042. gocql driver with these changes was released just yesterday (version v1.2.0). You are using version 1.1.0 so in order to leverage this feature, you need to update driver to version 1.2.0 first.

(1) https://github.com/gocql/gocql/pull/1635

Approach

Address translators should be pluggable because my way how I am translating addresses are not suitable for everybody so I provided my solution but it should be very easy to add any other translator and it should be possible just to switch between them via configuration.

My translator is called "fixed address translator" because from the point of view of the client, it will ever connect only to the very same domain name but the only thing which differs will be port - to recognise the instances. (each Cassadra node will run on different CQL port). That way we can make the difference between the nodes behind a load balancer when we hit different CQL port of load balancer address.

This is nothing special, we are already offering fixed address translator to Datastax Java driver https://github.com/datastax/java-driver/pull/1597

For gocql, this driver already offers address translator mechanism but you just need to add your own translator implementation in the code. For Temporal, as it is a black box from user's point of view, we need to implement address translator in temporal codebase and provide the way how to plug it into the driver on the Temporal's initialisation.

I was looking for a way how to achieve this and I noticed you are using "auth plugin" infrastructure. I basically copied this plugging logic and I accommodated it for address translator case - this PR is about it.

How did you test it?

I used your docker compose setup. The way I tested it was that I run all containers in one VPC but I removed Cassandra container. I have configured compose and its exposed env variables in such a way that it will connect to remote Cassandra cluster running elsewhere, behind loadbalancer / endpoint service in Amazon PrivateLink.

I have, of course, run temporal unit tests.

Changed docker compose scripts are here:

https://github.com/instaclustr/temporalio-docker-builds/commit/ed8f5a903cdddf24de0fb3d7217f88d6c5583ee1

This will likely need to be included into docker builds script as well.

Potential risks

Nothing is going to break when this feature is not used. This PR is no-op meaning the current depoyments are not affected. One needs to specifically enable this feature to see it in action.

Is hotfix candidate?

I assume this is new feature, not hotfix, and Temporal community should be informed about this feature.

Error: Add search attribute failed

Expected Behavior

I should be able to add a new search attribute "UserID" of type Keyword to Temporal for filtering.

Actual Behavior

I initially receive an error when trying to add attribute. Upon listing added keys, I see the newly added key but it is of the wrong type (String).

Steps to Reproduce the Problem

Deploy the latest Temporal 0.26.0 with Elasticsearch enabled.
Add a new search attribute by running the following command: tctl --namespace default adm cl asa --search_attr_key UserID --search_attr_type 1
Observe the following error and stack trace:

bash-5.0# tctl  --namespace default adm cl asa --search_attr_key UserID --search_attr_type 1
Are you trying to add key [UserID] with Type [Keyword]? Y/N y

Error: Add search attribute failed.

Additional Questions

Now that I have an incorrect attribute added, is there any way to edit or remove it? Does the search attribute need to be registered explicitly by the CLI before it can be used elsewhere (go-sdk)? The docs mention something here but it's still a bit unclear: https://docs.temporal.io/docs/learn-workflow-filtering#search-attributes-go-client-usage

Repeated "New timer generated is less than read level" in logs after adding node to cluster
Expected Behavior

After adding a second node to a newly-bootstrapped one-node temporal cluster, logs should be generally quiet.

Actual Behavior

Instead, after adding the second node, I see "New timer generated is less than read level" repeated once per second in the logs of the original node (logs of second node are quiet). Full example log line:

{"level":"warn","ts":"2020-06-01T18:08:52.273-0700","msg":"New timer generated is less than read level","service":"history","shard-id":111,"address":"[redacted]:7234","wf-namespace-id":"892c1d1f-e202-49dc-bc77-97268a84c9ef","wf-id":"eae6d2bc-89fe-4ac5-a544-a8087e3deede","timestamp":"2020-06-01T17:14:41.689-0700","cursor-timestamp":"2020-06-01T18:08:53.265-0700","shard-update":"ShardAllocateTimerBeforeRead","logging-call-at":"shardContext.go:1130"}

Note that the IP address in the address field refers to the same node that is generating the log.

Steps to Reproduce the Problem

Set up a fresh Cassandra keyspace and ES index.

Boot a single Temporal node and create a test namespace.

Start a workflow/activity worker and start a workflow execution to test that it works.

Boot a second Temporal node and wait for it to finish joining the cluster.

Repeated log message should start.

I am not certain that step 3 is required, but this is what I did, so I'm detailing it here.

Specifications

Version: 0.23.1

Platform: Amazon Linux 2018.03 + Docker 18.09.9

More Information

After running tctl admin cluster describe against both Temporal nodes, I can see that they both have the same view of the cluster, and that they both see all four services on both nodes.

Prevent incorrect service discovery with multiple Temporal clusters
Is your feature request related to a problem? Please describe.

I run multiple separate Temporal clusters within a single k8s cluster. Each Temporal cluster has its own separate set of frontend, history, and matching services as well as persistence. Let's say I am running two Temporal clusters called "A" and "B" in a single k8s cluster. Note that in my setup, there are no networking restrictions on pods within the k8s cluster -- any pod may connect to any other pod if the IP address is known.

I recently encountered a problem where it appeared that a frontend service from Temporal cluster A was talking to a matching service from Temporal cluster B. This happened during a time where the pods in both of the Temporal clusters were getting cycled a lot due to some AZ balancing automation. It also happens that this particular k8s cluster is configured in such a way that pod IP address reuse is more likely than usual.

Both Temporal cluster A and B are running 3 matching nodes each. However, I saw this log line on Temporal cluster A's frontend service:

{"level":"info","ts":"2021-01-27T00:34:15.414Z","msg":"Current reachable members","service":"frontend","component":"service-resolver","service":"matching","addresses":"[100.123.207.80:7235 100.123.65.65:7235 100.123.120.28:7235 100.123.60.187:7235 100.123.17.255:7235 100.123.203.172:7235]","logging-call-at":"rpServiceResolver.go:266"}

This is saying that Temporal cluster A's frontend service is seeing 6 matching nodes, three from A and three from B. Yikes.

I believe what led to this is something like:

A matching pod in cluster A gets replaced, releasing its IP address. This IP address remains in cluster A's cluster_metadata table.

A matching pod is created in cluster B re-using this IP address.

An event occurs that causes a frontend in cluster A to re-read the the node membership for its matching nodes. It finds the original matching node's IP address still in the table and it can still connect to it even though it is actually now a matching node in cluster B.

Through this matching node in cluster B the the other cluster B matching nodes are located.

My fix for this is to make sure that each Temporal cluster has its own set of membership ports for each service. This would have prevented the discovery process in cluster A from seeing the pods in cluster B since it would be trying to connect on a different port.

Describe the solution you'd like

It may be possible to prevent this by including a check that a given node is indeed part of the correct cluster before adding it to the ring.

Describe alternatives you've considered

I don't believe our k8s environment has an easy way to prevent this using networking restrictions.

Support for pluggable authorizers

Is your feature request related to a problem? Please describe. I'm under the impression that the authorization interface requires user to recompile Temporal.io in order to add an implementation.

https://github.com/temporalio/temporal/blob/master/common/authorization/authorizer.go

Describe the solution you'd like I would like to implement a generic authorizer that loads a plugin using the golang plugin interface. Or a generic authorizer that calls an external Open Policy Agent server. This way I can plugin authorization rules wthout having to rebuild the cadence code.

What do you think? I'm available to contribute a merge request if you think it could be a valuable change. I would include i nthe merge request also support for checking the TaskQueue (extending the Attributes struct).

Add RDS IAM auth plugin for SQL drivers
Signed-off-by: Alexander Mays [email protected]

What changed?

a new environment variable to the CLI: SQL_AUTH_PLUGIN=rds-iam-auth

a new flag arg to the CLI: --sql-auth-plugin rds-iam-auth

2 new docker template variables: authPlugin: {{ default .Env.SQL_AUTH_PLUGIN "" }} and authPlugin: {{ default .Env.SQL_VIS_AUTH_PLUGIN "" }}

a new SQL configuration attribute authPlugin:

sql: pluginName: "mysql" databaseName: "temporal" connectAddr: "127.0.0.1:3306" connectProtocol: "tcp" user: "temporal" password: "temporal" maxConns: 20 maxIdleConns: 20 maxConnLifetime: "1h" authPlugin: plugin: "rds-iam-auth" timeout: "10s"

Why? Amazon RDS supports implicit auth using the execution role of an underlying compute resource. Some best practices steer users towards configuring RDS databases without a password and relying entirely on IAM auth.

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.html

https://community.temporal.io/t/aws-rds-postgresql-iam-authentication/3168

The AWS SDK can derive credentials from an execution role (or other CredentialProviders) and then generate a one-time token (password) every time a new connection is created.

How did you test it?

Added 3 new unit test cases to test the basic call sites

Verified temporal-sql-tool [create|setup|update] against a production instance of MySQL 8.0.23 and Postgres 13.4

Verified temporal-server [start] against a production instance of MySQL 8.0.23

Potential risks

The plugin is opt-in. Default behavior should be unaffected.

RDS IAM integration adds overhead for creating a new connection on the client, as well as on the database server. Amazon recommends keeping new connection requests under 200/s otherwise the database can begin throttling and even drop existing connections. I did not witness any connection churn during my tests, but I am a new Temporal user so I might not be aware of behavior at scale. The AWS Guide linked above has more information on the limitations and considerations.

Refactor Dockerfiles to better support ARM
What changed?

Use ARG for base docker images for easier debug/test.

Separate base-builder and base-ci-builder. The later has some tools which are not available on ARM yet and required only by CI builds. base-builder has very minimum required to build production version and has full ARM support.

Replaced binary of jwilder/dockerize with build from source from a git clone. Worth looking at a replacement or removal, but this preserves the existing use of dockerize templates for now.

Add corresponding Makefile targets to build with docker buildx.

Update docker/base-images/README.md.

Partial "fix" for #1305.

Build base-server for both arm64 and x86 container images with this command:

docker buildx build \ --build-arg TARGET=auto-setup \ --platform linux/arm64,linux/amd64 \ -f base-server.Dockerfile \ .

or

make base-server-x DOCKER_IMAGE_TAG=1.3.0

Why? Ability to run Temporal on AWS Graivton2 instances.

How did you test it? Build locally for different platforms.

Potential risks Might brake x86 docker images.

Is hotfix candidate? No.

Fix workflow ID reuse when running on ScyllaDB

What changed?

Fix an issue where the history service would get stuck in a loop when reusing workflow ID's on top of ScyllaDB.

Why?

Closes https://github.com/temporalio/temporal/issues/2683.

How did you test it? First reproduced the issue by running Temporal on top of Scylla locally; then verified that the change fixed the issue. Ran Cassandra persistence tests to ensure that this change didn't break anything else.

Potential risks As noted in the linked issue:

Not sure if there are conditions when Cassandra might also return nullable rows.

If there are cases where we should be handling nil rows as real errors, this change would break that.

Is hotfix candidate? Yes.

add optional explicit ForceTLS option to ClientTLS config

What changed? Add an optional useTls config property under publicClient to override whether or not TLS is used when connecting to the endpoint, regardless of the tls.frontend.server configuration.

Why? To fix issue 2035, which I encountered while setting up Temporal under ECS in AWS with a frontend ALB load balancer terminating TLS.

How did you test it? Tested locally and in my nonproduction environment.

Potential risks Worker role may fail to start if property is incorrectly set. Not setting the property at all results in the status quo behavior where TLS is based on configuration present in tls.frontend.server.

Is hotfix candidate? No

Note that I'm a newb to golang and am more than open to recommendations here.

Inject or plug in a customized Authorizer without having to build the temporal image by users

Is your feature request related to a problem? Please describe. We need some namespace level authorization. The best bet currently is https://github.com/temporalio/temporal/blob/release/v1.8.x/cmd/server/main.go#L154. However, we'd have to implement our authorizer in temporal's repo and build the docker image from that.

Describe the solution you'd like Ideally, as a customer, we don't have to build our own image. We can just use images like temporalio/auto-setup:1.8.2 and inject or plug in our own implementation of the authorizer somehow.

Describe alternatives you've considered We're currently modifying temporal open source project and build our own image.

Fix datarace in forwarder_test

What changed? A loop variable is captured in a groutine here, so the test is non-deterministic. A golangci-linter pointed this out to me.

Why? Ensure this test is working correctly.

How did you test it? Reran the linter.

Potential risks None, just a test

Handle wrapped errors in task executable
What changed?

Check wrapped errors when handling task execution error

Why?

So that we can wrap errors in task execution logic and log more informative error messages.

How did you test it?

Existing test

Potential risks

If there's any existing error wrapping in task processing, error handling logic may go wrong. But I searched two ways of error wrapping:

Unwrap() error method: no result in our code base

%w: either not related to task processing or the error get wrapped is not one of the error or error types we are checking for task executable.

No.

CRON scheduled workflow with ContinueAsNew
Expected Behavior

Hi, I'm trying to use a CRON scheduled workflow together with the Continue-As-New feature. When I trigger a CRON workflow, inside trigger Continue-As-New a few times, I expect it to schedule a new CRON run after the workflow is finished.

According to https://github.com/temporalio/temporal/issues/2146 this should work, but it does not for me.

Actual Behavior

The workflow just ends and no new CRON run is scheduled

Steps to Reproduce the Problem

Clone https://github.com/benkelukas/temporal-cron-continue-as-new

Run docker-compose build

Run docker-compose up

Run docker-compose exec app php app.php periodic:start

Wait for 2 Continue-As-New triggers

Observe Workflow being completed and no new CRON run scheduled

Releases(v1.19.0)

v1.19.0(Dec 1, 2022)
Release Highlights

Schema changes

Before upgrading to your Temporal Cluster to release v1.19, you must upgrade your storage schema version to the following:

MySQL schema version 1.9

PostgreSQL schema version 1.9

Cassandra schema version 1.7

Use the appropriate schema upgrade tool to upgrade your schema version. For details, see https://docs.temporal.io/cluster-deployment-guide#upgrade-server.

Note that schema version is not the same as the storage type (database) version.

Golang version

Upgraded golang to 1.19.

tctl

tctl release with v1.17.2 (https://github.com/temporalio/tctl/releases/tag/v1.17.2).

Metric

A major refactoring has been done in the metrics code. Both metrics.Client and metrics.Scope are replaced by metrics.metricsHandler.

Customized metricsHandler is also supported by using temporal.WithCustomMetricsHandler .

Deprecated metrics

All metrics that have the suffix _per_tl are deprecated.

Improvements and fixes

Clean up mutable state when Workflow is closed

When the Workflow is closed, you can trigger a cleanup to remove Memos and Search Attributes from the mutable state. This helps reducing the size of the mutable state for closed Workflows. However, because the cleanup deletes data, it’s best to pair Advanced Visibility with Elasticsearch to ensure that Search Attributes can be retrieved. This feature is controlled by the dynamic config history.visibilityProcessorEnableCloseWorkflowCleanup.

Count limits for pending Child Workflows, Activities, Signals, and cancellation requests

This change adds a new system protection limit for the maximum number of pending Child Workflows, pending Activities, pending Signals to external Workflows, and pending requests to cancel external Workflows. Operators can set different values for those new limits via the dynamic config. The default is currently 50,000 for each value.

limit.numPendingChildExecutions.error limit.numPendingActivities.error limit.numPendingSignals.error limit.numPendingCancelRequests.error

Maximum number of concurrent pollers

The dynamic config frontend.namespaceCount controls how many concurrent pollers are allowed to connect to Temporal Server. Currently, this limit applies to the total number of pollers; that is, Activity plus Workflow pollers. In v1.19.0, this limit now applies to the number of pollers per type; that is, Activity and Workflow pollers won’t compete with each other for a connection to Temporal Server.

Batch deletion

The batch delete operation is now support in the batch operation API. Use BatchOperationDeletion option in the StartBatchOperationRequest for a batch delete operation.

History task processing

Default implementation

Host-level Task scheduler is now enabled by default, meaning the default value of history.[timer|transfer|visibility]ProcessorEnablePriorityTaskScheduler is true.

Multi-cursor queue implementation is now enabled by default, meaning the default value of history.[timer|transfer|visibility]ProcessorEnableMultiCursor is true.

Rate limiting

Added priority rate limiter for Task processing. By default this rate limiter is disabled but can be enabled by setting history.taskSchedulerEnableRateLimiter to true. The rate limiter should be enabled only when multi-cursor queue implementation is enabled.

The rate is controlled by history.taskSchedulerMaxQPS for per-host limit and history.taskSchedulerNamespaceMaxQPS for per-Namespace limit. All queues (timer, transfer, visibility) share the same limit. Please note that deletion Tasks have lower priority when consuming rate limit tokens and do not count against the per-Namespace limit.

The default value for the preceding two configurations is 0, which means they will fall back to and use the value specified by history.persistenceMaxQPS and history.persistenceNamespaceMaxQPS.

Metrics

task_latency_processing_nouserlatency, task_latency_userlatency, task_latency_nouserlatency, and task_latency_queue_nouserlatency are removed.

New task_latency_user metric, which captures the latency for acquiring Workflow lock in a single Task Execution attempt.

History Scavenger

A retention validation on workflow has been added in the history scavenger. This feature is enabled by fault with worker.historyScannerVerifyRetention. A default grace period on this retention validation is 90 days + namespace retention time. The grace period is configurable by worker.executionDataDurationBuffer.

This release has a bug that prevents server startup when running in a single-node configuration. Please use v1.18.3 instead.

Release Highlights

This patch releases fixes a few small bugs in namespace migration. It also has two changes to scavengers: the history scavenger is now enabled on SQL persistence, and the execution scavenger now finds mutable state that's past its retention timeout.

v1.18.0(Sep 19, 2022)
Release Highlights

Upgrade action item summary

Before upgrade

If you’re using ES v6: do not deploy this version until after moving to ES v7 or later

If you’re using ES v7+: upgrade schema to include new builtin search attributes (see Schedules section below)

If you used the experimental Schedules feature in 1.17: delete all schedules and recreate them after upgrading

After upgrade

Change dynamic config matching.useOldRouting to false on all nodes as close in time as possible. This will cause temporary matching disruption during the propagation.

Consider enabling host-level worker pool and multi-cursor task processing (see Task processing section below)

Consider setting persistence rate limits (see Persistence rate limiting section below)

Elasticsearch v6 support is removed

Elasticsearch v7 became the default supported version in 1.12.0 release. In 1.18.0, Elasticsearch v6 support is completely removed. If you are still using Elasticsearch v6, don't upgrade to 1.18.0. Upgrade Elasticsearch first following the migration guide.

Along with v6 support removal, we added Elasticsearch v8 support. Elasticsearch v8 doesn’t have breaking changes that affect Temporal.

Batch API

This release introduces new batch operation APIs in the Frontend Service. The feature is enabled by default.

StartBatchOperation: Start a batch operation.

StopBatchOperation: Stop a running batch operation.

DescribeBatchOperation: Get detail information about a batch operation.

ListBatchOperations: List all the batch operations.

By default, the APIs support one concurrent operation per Namespace. This value is configurable by dynamic config: frontend.MaxConcurrentBatchOperationPerNamespace.

Use DescribeBatchOperation or metrics batcher_processor_requests and batcher_processor_errors to monitor the progress of batch operations.

Cluster API

The following Cluster APIs moved from the admin service to the operator service. Those APIs will be deprecated in the admin service in a future release.

AddOrUpdateRemoteCluster: Add or update a connection configuration to a remote Cluster.

RemoveRemoteCluster: Remove a connection to a remote Cluster.

ListClusters: List the configuration of all connected Clusters.

Task processing

Host level task scheduler

Host level task scheduler now uses separate task channels for each namespace for better resource isolation.

Deprecated the dynamic config history.[timer|transfer|visibility]TaskHighPriorityRPS.

Multi-cursor queue

New multi-cursor queue implementation for better resource isolation and handling cases not covered by host-level task scheduler: too many pending tasks, stuck queue ack level, etc.

The new implementation can be enabled by setting the value of dynamic config history.[timer|transfer|visibility]ProcessorEnableMultiCursor to true.

The host-level worker pool for the corresponding queue should also be enabled, otherwise the above dynamic config won’t take effect. This can be done by setting history.[timer|transfer|visibility]ProcessorEnablePriorityTaskScheduler to true.

Task Loading

The dynamic config history.[timer|transfer|visibility]ProcessorMaxPollHostRPS can be used to limit the throughput of the queue processor. This is very useful for recovering from a persistence outage which leads to a large task queue backlog in persistence. Set the value to a small number and gradually increase to ensure a smooth draining of the backlog. By default, value for this config is 0 and will fallback to 30% of the history.persistenceMaxQPS for transfer and timer queue and 15% for visibility queue.

Metrics

New task processing related metrics are added for better visibility.

task_latency_load: measures the duration from task generation to task loading (task schedule to start latency for persistence queue).

task_latency_schedule: measures the duration from task submission (to task scheduler) to processing (task schedule to start latency for in-memory queue).

queue_latency_schedule: measures the time it takes to schedule 100 tasks in one task channel in the host level task scheduler. If there are less than 100 tasks in the task channel for 30s, the latency will be scaled to 100 tasks upon emission. NOTE: this is still an experimental metric and is subject to change.

Retry behavior

Consolidated retry logic for APIs calls to two places: service handler (by an interceptor) and service client for calling other temporal services or persistence. Limited retry maximum attempts and removed retry logic in other places to avoid potential retry storm.

Persistence rate limiting

Persistence layer rate limiter prioritizes user requests (e.g. start workflow, signal workflow, etc.) over system background requests (e.g. task loading, requests incurred by task processing, replication, etc.)

Persistence max QPS for each namespace can be set by tuning the dynamic config [frontend|history|matching|worker].persistenceNamespaceMaxQPS. By default, this value is 0 and will fallback to the overall host persistence QPS set by [frontend|history|matching|worker].persistenceMaxQPS.

Persistence metrics persistence_requests, persistence_latency and persistence_error* now also contains namespace tag for better observability.

UpsertMemo

This release adds UpsertMemo to modify existing workflow memo. It works similarly to UpsertSearchAttributes. However, on the visibility side, the memo is updated only when used with advanced visibility (i.e. Elasticsearch). When used with standard visibility (SQL databases), the memo is not being updated currently, and the workflow memo can be retrieved correctly only from the mutable state (that is, you can call DescribeWorkflowExecution to retrieve it).

Matching routing

Task queues are now distributed among matching nodes based on namespace and type, for better load balancing. This change is disabled by default to avoid disruption during the upgrade. After upgrading to 1.18, you should make a dynamic config change on all nodes simultaneously to set matching.useOldRouting to false. You can use the following snippet:

# Remove this after upgrading to 1.19: matching.useOldRouting: - value: false

This change will cause a short disruption to Task dispatch as nodes reload the dynamic config and then Task Queues get moved between matching nodes. You’ll also see some persistence errors in logs for a few minutes.

We plan to make this routing the default in 1.19, so if you don’t make the dynamic config change, it’ll happen during the next upgrade.

Schedules

A few incompatible changes were made to the Schedules feature, which was introduced as experimental in 1.17. If you have created any Schedules, you should delete them before upgrading to this release, and recreate them after the upgrade.

The Schedule feature is now enabled by default.

If you're using Advanced Visibility (i.e. Elasticsearch), Schedules don’t appear in Workflow lists anymore. If you’re not using Elasticsearch, Schedules continue to appear in Workflow lists for now.

There is one new builtin search attribute to support Schedule visibility. You can add it to Elasticsearch by running the upgrade script from the server repo. See the top of the script for environment variables to use to point it at your Elasticsearch. You can do this before or after the upgrade, but before creating any Schedules. (If you didn’t perform the v2 upgrade when upgrading to 1.17, which also added search attributes for Schedules, also do that now.)

Frontend connections

Update: these release notes previously described a new method of making internal frontend connections. This new method works in many, but not all, server configurations (specifically related to mTLS and custom authorizers). To make it work for all configurations, we're going to make some more changes to the feature. In the meantime, there's no need to change any configuration. (If you've already made the config change that was suggested here and it's working, there's also no need to change it back.)

Maximum retention

The maximum Namespace retention limit of 30 days is removed. Namespaces now can use any retention as needed, as long as the persistence has enough capacity for the storage.

Dynamic config interface

The dynamicconfig.Client interface was changed and simplified.

If you’re using Temporal with our pre-build container images or binaries, there’s nothing to do.

If you’re building your own Temporal binary and only refer to dynamicconfig.Client or dynamicconfig.NewFileBasedClient in your ServerOptions, you should be able to rebuild with no code changes.

If you’ve written a custom dynamic config implementation, you’ll need to change it to the new interface. This should be pretty straightforward, but if you have any questions, please contact us; we can help.

v1.17.4(Aug 17, 2022)
Release Highlights

This release includes bug fixes for Archival and Retry logic, and removes 30 days max Retention Period limit.

IMPORTANT NOTE FOR ARCHIVAL USERS If you are using the Archival feature and if v1.17.4 of the History Service runs with an older version of the Worker Service during the upgrade, it is possible to have a "dangling Workflow mutable state" where the Event History has been deleted. To avoid that when upgrading to this release, perform the following steps:

Stop the old version of the Worker Service.

Deploy this patched release.

Start the Worker Service after the upgrade.

v1.17.0(Jun 21, 2022)
IMPORTANT

This release contains a potential shard lock issue. Do not use this release. Use v1.17.4 instead.

Release highlights

Elasticsearch schema changes

Elasticsearch schema v2 has been added.

The Elasticsearch schema v2 supports new built-in Search Attributes. This schema only adds new mappings, it is not a full reindex.

Use the v2 schema upgrade script schema/elasticsearch/visibility/versioned/v2/upgrade.sh. This can be done before or after upgrading to this release, but it must be done before using the experimental Scheduled Workflow feature.

Metrics

Multiple interfaces in the metrics package are deprecated. The following interfaces are scheduled to be removed in v1.18.0:

common/metrics/interfaces.go

UserScope

Scope

Client

Reporter

Initial implementation to replace these interfaces is now:

common/metrics/metrics.go

MetricsHandler

Histogram metrics use per unit bucket instead of latency unit bucket to emit metrics. In previous releases, the histogram metrics have to x1000 as they are using milliseconds unit. With the per unit bucket update, there is no need to have the x1000 compensation for Dimensionless unit and Bytes unit metrics.

common/metrics/config.go

defaultPerUnitHistogramBoundaries

New metrics service_error_with_type is added for all service errors. It included error_type as tag. The existing metrics service_errors_<FOR_EACH_SPECIFIC_ERROR_TYPE> are deprecated and will be removed from future release. Example of such existing metrics. New metrics persistence_error_with_type is added for all persistence errors. It included error_type as tag. The existing metrics persistence_errors_<FOR_EACH_SPECIFIC_ERROR_TYPE> are deprecated and will be removed from future release. Example of such existing metrics.

Workflow Execution deletion

Operator Service now exposes the new DeleteWorkflowExecution API, which accepts the name of a Namespace and a Workflow Execution. The Workflow Execution can be in any state. If it is Running, it will be terminated first. The API is exposed via tctl (version >=1.17.0-alpha.2):

$ tctl config set version next $ tctl workflow delete --workflow-id my_workflow $ tctl workflow delete --workflow-id my_workflow --run-id my_run_id

If --run-id is not specified, the latest Workflow Execution will be deleted.

Namespace deletion

Operator Service now exposes the new DeleteNamespace API, which accepts the name of a Namespace to delete. Be very careful with this API: it can’t be undone. The API is exposed via tctl:

$ tctl config set version next $ tctl namespace delete --name my_namespace_name

Namespace deletion is implemented using a system Workflow that is run by a system Worker. It is an asynchronous process, but the Namespace name can be reused as soon as API returns:

The Namespace is marked as deleted and renamed to a temporary name. After the DeleteNamespace API returns, the name can be reused (that is, a Namespace with the same name can be created).

All Workflow Executions in the deleted Namespace are deleted asynchronously from the database using the DeleteWorkflowExecution API described earlier.

The Namespace is deleted from the database.

Please note: this feature is still under active testing.

Host-level priority Task processing

New Task processing framework in History service for multi-tenancy. This feature is disabled by default in v1.17 and will be enabled in a future release.

Improved Task retry mechanism to avoid Tasks occupying a Worker goroutine for an extended period of time and blocking the entire queue.

Configuration for enabling host-level Task Worker pool. Example of dynamic config to enable them:

history.timerProcessorEnablePriorityTaskScheduler: - constraints: {} value: true history.transferProcessorEnablePriorityTaskScheduler: - constraints: {} value: true history.visibilityProcessorEnablePriorityTaskScheduler: - constraints: {} value: true

Configuration for Worker pool size (history.timer/transfer/visibilityProcessorSchedulerWorkerCount) for controlling total traffic sent downstream.

Configuration for adjusting high-priority Task quota allowed for each Namespace (history.timer/transfer/visibilityTaskHighPriorityRPS).

Configuration for Task processing round-robin weights (history.timer/transfer/visibilityProcessorSchedulerRoundRobinWeights) among various priorities.

New task_priority tag for Task processing metrics.

Scheduled Workflows (experimental)

Scheduled Workflows are a new feature that's more flexible than the existing CronSchedule. They're disabled by default in this release, but you can enable them with dynamic config settings. See more docs [here].

SQLite persistence

The SQLite module was replaced with a purego implementation. CGO is no longer required to use SQLite persistence. This means that you can use binaries attached to this release to run local server for development. Just download archive corresponding to your OS and architecture (Mac M1 works!), unzip it, and run server locally without docker-compose and any other dependencies with simple command:

$ ./temporal-server --env development-sqlite start

Release Highlights

Schema changes

Before upgrading to your Temporal Cluster to this release 1.16, you must upgrade your storage schema version to the following:

MySQL schema version 1.8

PostgreSQL schema version 1.8

Cassandra schema version 1.7

Use the Schema Upgrade Tool to upgrade your schema version. How to use the Schema Upgrade Tool: Upgrade Server version.

Note that schema version is NOT the same as the storage type (database) version, see “Latest SQL database support” below.

Docker Version

This version (1.16) will be the last version that we build our images based on Alpine 3.13. In the next release (1.17), we are going to upgrade our base image to use Alpine 3.15, which may not be able to run on docker versions lower than 20.10.0. Please check more details here.

Golang version

Upgraded golang to 1.18

Tctl

tctl implementation has been moved to a new repository

API

New Operator service for managing namespace and search attribute

New DeleteNamespace API in OperatorService. Please note that the delete namespace feature is still under active development and not production ready

New TERMINATE_IF_RUNNING workflowIdReusePolicy. If a workflow is running using the same workflow ID, this policy will terminate it and start a new one; otherwise, the behavior is the same as ALLOW_DUPLICATE

RequestCancelWorkflowExecution and RequestCancelExternalWorkflowExecutionCommand now supports reason field. The reason will also be recorded in WorkflowExecutionCancelRequestedEvent and RequestCancelExternalWorkflowExecutionInitiatedEvent

NonRetryableErrorTypes now supports TemporalTimeout:StartToClose and TemporalTimeout:Heartbeat for customizing retry behavior upon timeout failure

New last_heartbeat_details field in RespondActivityTaskFailedRequest and RespondActivityTaskFailedByIdRequest

New activity_failure_include_heartbeat system capability indicating if RespondActivityTaskFailed API supports including heartbeat details

New ListHistoryTasks API in admin service for listing transfer, timer, replication and visibility tasks

Removed per service Metrics config

New RemoteClusters field for controlling TLS settings for takling to remote cluster

New SKIP_DB_CREATE environment variable for skipping DB creation in auto-setup

If you use SQL persistence layer, please add the following configuration to your dynamicconfig file so that the ID length limit matches the actual limit used in sql schema. A sample configuration file can be found here
limit.maxIDLength: - value: 255 constraints: {}

Metric

New matching service task_lag_per_tl metric for estimated task lag

New service_name metrics tag

New matching task_write_throttle_count and task_write_latency metrics

New worrkflow_task_attempt metric

Schema changes

This release contains a bug that could potentially lose tasks in failure scenario when history pods are not stable and keep bouncing between multiple nodes. Please upgrade to latest patch release 1.14.3 or later.

Before upgrading to your Temporal Cluster to this release 1.14, you must upgrade your storage schema version to the following:

MySQL schema version 1.7
PostgreSQL schema version 1.7
Cassandra schema version 1.6

Use the Schema Upgrade Tool to upgrade your schema version. How to use the Schema Upgrade Tool: https://docs.temporal.io/docs/server/versions-and-dependencies/#upgrade-your-version-of-temporal.

Note that schema version is NOT the same as the storage type (database) version, see “Latest SQL database support” below.

tctl

tctl batch - Added a flag to limit amount of goroutines: --concurrency.
tctl admin - Removed direct database connection and switched to Admin API. Removed flags related to database connection.
Added a cluster command to upsert or remove remote cluster. This feature is still in development and may change in future release.
Renamed --min/max_read_level flag to --min/max_task_id when listing cluster tasks.
tctl namespace - Added a flag to promote a local namespace to a global namespace: --promote-namespace.
Removed commands related to Elasticsearch.
Removed cluster metadata command.

Metrics

Added option to configure histogram buckets per unit type (milliseconds, bytes, dimensionless). Existing metrics now have assigned relevant unit types. Example.
Added config option to exclude reported metric tags. Example.
Upgraded uber-go/Tally to v4.0.1.
Upgraded opentelemetry version to v1.1.0.

Latest SQL database support

Latest version of MySQL and PostgreSQL were tested. Temporal now officially supports MySQL 8 starting from version 8.0.19 and PostgreSQL 13 starting from version 13.5.

Multi-Cluster

Cluster metadata definition is migrating from application static config file to a new DB table. Cluster metadata will be initialized once when the service first starts up. Future remote cluster metadata modifications need to be done via tctl admin cluster tool. Example.

Other

Server will fail to start if dynamic config is malformed. Previously, default config was used if errors occurred.
Upgraded golang to 1.17.
Added safety check for empty JWT source URIs.
Added Handover ReplicationState for graceful failover. This feature is still in development and will change in a future release.

Improvements/Fixes

Fix unexpected matching GetTasks call growth on low-traffic task queues.
Reduced overhead due to unloading history shards during short database unavailability.
Limited Elasticsearch document _id to 512 bytes (#2112).

Internal refactoring

Adopted uber/fx for server initialization and dependency injection.
