Andrew Charlton, Staff Software Engineer at Timescale, explains how they replaced Kubernetes StatefulSets with a custom operator called Popper for their PostgreSQL Cloud Platform.
You will learn:
- Why StatefulSets fall short for managing high-availability PostgreSQL clusters, particularly around pod ordering and volume management
- How Timescale's instance matching approach solves complex reconciliation challenges when managing heterogeneous database workloads
- The benefits of implementing discrete, idempotent actions rather than workflows in Kubernetes operators
Watch (or listen to) it here: https://ku.bz/fhZ_pNXM3
🌟 This episode is brought to you by [MetalBear] mirrord — run local code like in your Kubernetes cluster without deploying first https://ku.bz/lHtPqsdjq
