Server Versioning

The MySQL Server included in HeatWave on AWS uses a versioning system consisting of three numbers, an update version, and the -cloud suffix. Using 8.4.0-u2-cloud as an example:

  • First number: The major release number (8 in the example).

  • Second number: The minor release number (4 in the example).

  • Third number: The patch number (0 in the example). This is incremented for each new release.

  • uN : The HeatWave-specific update number (u2 in the example). Fixes and feature development for the cloud version of MySQL Server are delivered according to a different schedule than the on-premise version.

  • cloud: Suffix indicating this version of MySQL Server was built for the cloud only.

To retrieve the MySQL Server version number, connect to your DB System using a MySQL client, and run SELECT @@version;. The following example shows the command and its typical output:

mysql> SELECT @@version; +-----------------+ | @@version | +-----------------+ | 8.4.0-u2-cloud | +-----------------+
