Additional Requirements

Depending on your local configuration, some components of Couchbase Server may have additional system requirements.

Java Runtime Environment (JRE) — Analytics Service Only

The Analytics Service requires a Java Runtime Environment to be installed. OpenJDK 11 is installed by default when you install Couchbase Server — you do not need to install any additional prerequisites to use the Analytics service. However, if necessary, you can specify an alternative JRE for the Analytics Service when you initialize a cluster. If you plan to use an alternative JRE for the Analytics service, note that the following versions are supported.
