Support for Percona XtraDB Cluster in ProxySQL (Part One)

How native ProxySQL stands in failover support (both v2.0.15 and v2.1.0)

In recent times I have been designing several solutions focused on High Availability and Disaster Recovery. Some of them using Percona Server for MySQL with group replication, some using Percona XtraDB Cluster (PXC). What many of them had in common was the use of ProxySQL for the connection layer. This is because I consider the use of a layer 7 Proxy preferable, given the possible advantages provided in ReadWrite split and SQL filtering. 

The other positive aspect provided by ProxySQL, at least for Group Replication, is the native support which allows us to have a very quick resolution of possible node failures.

MySQL 8.0.22 Replication Enhancements

MySQL 8.0.22 was released roughly a week ago. It includes some nice additions to replication that we would like to call out. Here they are:

  • Automatic Asynchronous Replication Connection Failover (WL#12649). This work, by Hemant Dangi, implements a mechanism in asynchronous replication that makes the replica automatically try to re-establish an asynchronous replication connection to another replication source, in case the current connection gets interrupted;
  • New terminology for replica related statements (WL#14171).
