Galera Cluster comes with many notable features that are not available in standard MySQL replication (or Group Replication); automatic node provisioning, true multi-master with conflict resolutions and automatic failover. There are also a number of limitations that could potentially impact cluster performance. Luckily, if you are not aware of these, there are workarounds. And if you do it right, you can minimize the impact of these limitations and improve overall performance.
