features:
- |
When deploying a new HA overcloud, the mysql/galera service can now be
configured to use mariabackup for State Snapshot Transfers (SST) by
configuring the new Heat parameter `MysqlGaleraSSTMethod`. Mariabackup
SST uses a dedicated SQL user with the appropriate grants to transfer
the database content across nodes. The user credentials can be
configured via two additional Heat parameters `MysqlMariabackupUser`
and `MysqlMariabackupPassword`.
upgrade:
- |
The new support for mariabackup SST for the mysql/galera service is
currently limited to new overcloud deployments. Doing a stack update
to change SST method from rsync to mariabackup or the other way around
is currently not supported.
