Sergey Pronin
Sergey Pronin Percona XtraDB Cluster Operator architecture decisions
Percona XtraDB Cluster Operator is a drop in replacement for MySQL Enterprise with sync replication running on Kubernetes. It automates the creation, alteration, or deletion of members in your Percona XtraDB Cluster environment. It can be used to instantiate a new Percona XtraDB Cluster replica set, or to scale an existing environment.

In this talk we will cover various architecture decisions we made when building PXC Operator. There are lots of differences between how it can be done on regular VMs and in k8s: PITR implementation, autorecovery, retention policies, haproxy/proxysql & proxy protocol.

Sergey is a passionate technology “driver”. After graduation worked in various fields: internet service provider, financial sector and M&A business. Main focal points were infrastructure and products around it. At Percona as a Product Owner drives forward Kubernetes and Cloud databases solutions.
