25.3. JDBC batching

<div class="paragraph">

JDBC allows us to batch multiple SQL statements and to send them to the database server into a single request.
This saves database roundtrips, and so it [reduces response time significantly](https://leanpub.com/high-performance-java-persistence/read#jdbc-batch-updates).

Not only `INSERT` and `UPDATE` statements, but even `DELETE` statements can be batched as well.
For `INSERT` and `UPDATE` statements, make sure that you have all the right configuration properties in place, like ordering inserts and updates and activating batching for versioned data.
Check out this article for more details on this topic.
