We recently upgraded from Postgres 11.9 to 15.3 with zero downtime by using logical replication, a suite of support noscripts, and tools in Elixir & Erlang’s BEAM virtual machine. This post will go into far too much detail explaining how we did it, and considerations you might need to make along the way if you try to do the same.

This is the story of how we upgraded our fleet of 1200+ MySQL hosts to 8.0. Upgrading the fleet with no impact to our Service Level Objectives (SLO) was no small feat–planning, testing and the upgrade itself took over a year and collaboration across multiple teams within GitHub.

The article from QuestDB discusses their transition to a Kubernetes Operator for their cloud operations. The switch involves moving from a provisioner-based system to a Kubernetes Operator, which manages complex operations and orchestrates features like automatic node failure recovery, High Availability, and Cold Storage. This new system simplifies provisioning by reducing code complexity and improving unit testing. It also offers benefits like auto-healing, easier upgrades, and improved control plane locality. The operator is designed to be a drop-in replacement for their current system, ensuring seamless transition and enhanced automation capabilities.
