@ExpectJdbcBatching

Verify that inserts, deletes and updates are processed in JDBC batches having batchSize elements. You may sometimes think that you are using JDBC batching but in fact not (Paper 1, Paper 2)! Batching of inserts, updates and deletes allows to reduce the number of roundtrips to the database which can dramatically impact application performance. You can decide to batch all inserts, updates, delete. Prior to Hibernate 5.2, batching, when enabled with a hibernate.jdbc.batch_size property stricly positive, was applied to all inserts, updates and deletes (from Hibernate 5.2 it is also possible to override the batch size value for a given session).

🔧 Parameters
