Because database + * access is known to be an expansive operation, using L2 cache may improve + * performance dramatically. + * <p> + * This example defines 2 entity classes: {@link User} and {@link Post}, with + * 1 <-> N relation, and marks them with appropriate annotations for Hibernate + * object-relational mapping to SQL tables of an underlying H2 in-memory database. + * The example launches node in the same JVM and registers it in + * Hibernate configuration as an L2 cache implementation. It then stores and + * queries instances of the entity classes to and from the database, having + * Hibernate SQL output, L2 cache statistics output, and Ignite cache metrics + * output enabled. + * <p> + * When running example, it's easy to notice that when an object is first + * put into a database, the L2 cache is not used and it's contents is empty. + * However, when an object is first read from the database, it is immediately + * stored in L2 cache (which is Ignite In-Memory Data Ignite cluster in fact), which can + * be seen in stats output. Further requests of the same object only read the data + * from L2 cache and do not hit the database. + * <p> + * In this example, the Hibernate query cache is also enabled. Query cache lets you + * avoid hitting the database in case of repetitive queries with the same parameter + * values. You may notice that when the example runs the same query repeatedly in + * loop, only the first query hits the database and the successive requests take the + * data from L2 cache. + * <p> + * Note: this example uses {@link AccessType#READ_ONLY} L2 cache access type, but you + * can experiment with other access types by modifying the Hibernate configuration file + * {@code IGNITE_HOME/examples/config/hibernate/example-hibernate-L2-cache.xml}, used by the example. + * <p> + * Remote nodes should always be started with special configuration file which + * enables P2P class loading: {@code 'ignite.{sh|bat} examples/config/example-ignite.xml'}. + * <p> + * Alternatively you can run {@link ExampleNodeStartup} in another JVM which will + * start node with {@code examples/config/example-ignite.xml} configuration. + */ +public class HibernateL2CacheExample { + /** JDBC URL for backing database (an H2 in-memory database is used). */ + private static final String JDBC_URL = "jdbc:h2:mem:example;DB_CLOSE_DELAY=-1"; + + /** Path to hibernate configuration file (will be resolved from application {@code CLASSPATH}). */ + private static final String HIBERNATE_CFG = "hibernate/example-hibernate-L2-cache.xml"; + + /** Entity names for stats output. */ + private static final List<String> ENTITY_NAMES = + Arrays.asList(User.class.getName(), Post.class.getName(), User.class.getName() + ".posts"); + + /** + * Executes example. + * + * @param args Command line arguments, none required. + * @throws IgniteException If example execution failed. + */ + public static void main(String[] args) throws IgniteException { + // Start the node, run the example, and stop the node when finished. + try (Ignite ignite = Ignition.start("examples/config/example-ignite.xml")) { + // We use a single session factory, but create a dedicated session + // for each transaction or query.
