3.1.2.1.1 Server Versioning

The MySQL Server included in MySQL 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  |
+-----------------+
