Features
- Automatic schema creation and updates based on models
- Built in support for java types (Integer, String, Uuid, Boolean) with an API to add your own
- Support for OneToMany mappings with arraylist columns
- Out-of-the-box adapters for Sqlite (flat file), Sqlite (Memory) and HiariCP-MariaDB
- Dynamic SQL Dialects depending on the target platform
- Incredibly easy to use API
Performance
Tests ran on my main workstation, targeting a Sqlite flatfile and memory database. 
Examples
posts; @Column private UUID minecraftUserId = UUID.randomUUID(); @Column( name = "email", defaultValue = "[email protected]" ) private String emailAddress; } public class SocialPost extends StormModel { @Column( notNull = true ) private String content; @Column( keyType = KeyType.FOREIGN, references = {User.class} ) private Integer poster; } // create an instance Storm storm = new Storm(new SqliteDriver(dataFile)); // register one table storm.migrate(new User()); storm.migrate(new SocialPost()); storm.runMigrations(); // create a new user User mindgamesnl = new User(); mindgamesnl.setUserName("Mindgamesnl"); mindgamesnl.setEmailAddress("[email protected]"); mindgamesnl.setScore(9009); // save or update the user storm.save(mindgamesnl); // query for users Collection
justMindgamesnl = storm.buildQuery(User.class) .where("user_name", Where.EQUAL, "Mindgamesnl") .limit(1) .execute() .join();">
// create a model @Data @Table(name = "user") class User extends StormModel { @Column private String userName; @Column private Integer score; @Column( type = ColumnType.ONE_TO_MANY, references = {SocialPost.class}, matchTo = "poster" ) private List<SocialPost> posts; @Column private UUID minecraftUserId = UUID.randomUUID(); @Column( name = "email", defaultValue = "[email protected]" ) private String emailAddress; } public class SocialPost extends StormModel { @Column( notNull = true ) private String content; @Column( keyType = KeyType.FOREIGN, references = {User.class} ) private Integer poster; } // create an instance Storm storm = new Storm(new SqliteDriver(dataFile)); // register one table storm.migrate(new User()); storm.migrate(new SocialPost()); storm.runMigrations(); // create a new user User mindgamesnl = new User(); mindgamesnl.setUserName("Mindgamesnl"); mindgamesnl.setEmailAddress("[email protected]"); mindgamesnl.setScore(9009); // save or update the user storm.save(mindgamesnl); // query for users Collection<User> justMindgamesnl = storm.buildQuery(User.class) .where("user_name", Where.EQUAL, "Mindgamesnl") .limit(1) .execute() .join();
Usage with HikariCP
// hikari
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/simpsons");
config.setUsername("bart");
config.setPassword("51mp50n");
config.addDataSourceProperty("cachePrepStmts", "true");
config.addDataSourceProperty("prepStmtCacheSize", "250");
config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
Storm storm = new Storm(new HikariDriver(config));
