Percona Live Online

In this talk, I will discuss tools for advanced testing of Distributed Databases. Kubernetes offers new interesting ways on how to emulate failures or even chain of catastrophic events like disk or network errors.
Using https://chaos-mesh.org/ Chaos Mesh I will emulate failures in Percona XtraDB Cluster Kubernetes Operator and will show how Operator recovers (or not) from them. This benefits not only database kernel developers but also is helpful to understand how your application behaves under failures.
