Batch insert allows us to group multiple insert statements, and. This way, we can optimize the network and memory usage of our application. In this article, we created a simple example to show how we can benefit from Spring JDBC batch support for inserts. To enable the batch processing, we need to set the hibernate.jdbc.batch_size property to a number bigger than 0. hibernate.jdbc.batch_size = 5 If we're using Spring Boot, we can define it as an application property: spring.jpa.properties.hibernate.jdbc.batch_size = 5 To configure Session specific batch size, we can use setJdbcBatchSize () method. JDBC batching is a feature provided by the JDBC driver of your database. Activate JDBC Batching.
