This document provides information on configuring an external database.

Database Selection

Production instances of Confluence should use an external database. The default hSQL database has a risk of unrecoverable data loss due to not being transaction-safe.

Corruption is occassionally encountered after sudden power loss and can usually be corrected using this data recovery procedure. hSQL is still suitable for evaluation purposes, but the risk can only be eliminated by switching databases. External databases may also provide superior speed and scalability. Below is more information on selecting an external database.
