MySQL Master High Availability and Failover: more thoughts

Some months ago, Shlomi Noach published a series about Service Discovery.  In his posts, Shlomi describes many ways for an application to find the master.  He also gives detail on how these solutions cope with failover to a slave, including their integration with Orchestrator.

This is a great series, and I recommend its reading for everybody implementing master failover, with or without

ProxySQL Native Support for Percona XtraDB Cluster (PXC)

ProxySQL in its versions up to 1.x did not natively support Percona XtraDB Cluster (PXC). Instead, it relied on the flexibility offered by the scheduler. This approach allowed users to implement their own preferred way to manage the ProxySQL behaviour in relation to the Galera events.

From version 2.0 we can use native ProxySQL support for PXC.. The mechanism to activate native support is very similar to the one already in place for group replication.

In brief it is based on the table [runtime_]mysql_galera_hostgroups and the information needed is mostly the same:

  • writer_hostgroup: the hostgroup ID that refers to the WRITER

ProxySQL 1.4.14 and Updated proxysql-admin Tool

ProxySQL 1.4.14, released by ProxySQL, is now available for download in the Percona Repository along with an updated version of Percona’s proxysql-admin tool.

ProxySQL is a high-performance proxy, currently for MySQL,  and database servers in the MySQL ecosystem (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.

Replication Manager Works with MariaDB

Some time ago I wrote a script to manage asynchronous replication links between Percona XtraDB clusters. The original post can be found here. The script worked well with Percona XtraDB Cluster but it wasn’t working well with MariaDB®.  Finally, the replication manager works with MariaDB.

First, let’s review the purpose of the script. Managing replication links between Galera based clusters is a tedious task. There are many potential slaves and many potential masters. Furthermore, each replication link must have only a single slave. Just try to imagine how you would maintain the following replication topology:

A complex replication topology

The above topology consists of five clusters and four …
