This is the second part of a series where I look into how Java JDBC connections to PostgreSQL are working, to understand how to optimally implement them.

If you’ve landed on this article, it might be a good idea to read my first article as well, which gives an introduction and shares how JDBC communicates with PostgreSQL using simple and extended protocols.

This new article specifically explores batching. Batching for PostgreSQL JDBC is a property of the extended protocol. It uniquely allows you to send multiple statements in a single request.

Many Java applications use a database, and many use JDBC and PostgreSQL .

The latency of database usage is often important, yet, what exactly happens at the database level is unknown.

This article explains which options are available, what happens, and why.

Most importantly, it includes a small Java class that can be used and modified to execute specific database tasks, plus a description of how to use a utility (Wireshark ) to see what is actually happening.
