In this tutorial, we’ll walk through over ten scenarios where things can get complex with your Percona XtraDB Cluster (PXC)/Galera installation. We will break things in these scenarios and then you’ll have a chance to diagnose and fix them. Learn some of the most complex troubleshooting techniques. Scenarios: – New node fails to join cluster – Data sharing (Node catch up): SST, IST – Cluster restart failures – Data inconsistency – Delayed purging of the gcache – Network latency problems – Blocking transactions
