The latest release of the Percona Operator for MySQL, 1.1.0, is here.

Running stateful databases on Kubernetes means your backup and recovery story has to be airtight. A full nightly backup is fine, until the DBA drops a table at 2 PM and you’re looking at 14 hours of lost work. Or until your storage bill grows faster than your actual data because every backup is a …

Having a separate DR cluster for production databases is a modern day requirement or necessity for tech and other related businesses that rely heavily on their database systems. Setting up such a [DC -> DR] topology for Percona XtraDB Cluster (PXC), which is a virtually- synchronous cluster, can be a bit challenging in a complex Kubernetes environment.

With this release, Percona […]

Volume Expansion, a feature that became generally available since Kubernetes version 1.24, allows users to increase the capacity of their Persistent Volumes and underlying storage within Kubernetes. There is no need to use clouds’ UI or APIs to do that anymore. In our Operators, we use Stateful Sets – a Kubernetes resource that was designed for […]
