Author here. We didn't leave Clickhouse. It still drives most of what Posthog offers. I missed that bit of context in my post I admit. Instead we are looking into a new stack we can give customers so they can run their warehousing workloads on it instead of the centralized CH.
Stateless CH on Iceberg sounds interesting, we looked into it but Delta/Iceberg had other downsides for us.
