++ agreed.

ClickHouse Keeper was released as feature complete in December of 2021.

It runs thousands of clusters, daily, both in CSP hosted offerings (including our own ClickHouse Cloud) and at customers running the OSS release.

Never accept any claims at face value and always test. But, in this case, it is quite battle-hardened (i.e. the Jepsen tests run 3x daily https://github.com/ClickHouse/ClickHouse/tree/master/tests/j...).

That’s a strong endorsement. I wonder if there’s been any effect where it’s strongly tailored to the API surface area utilized by ClickHouse and there’s any gaps elsewhere

We hope not and try to keep in wire compatible for clients to interact (recently added dynamic reconfig, etc.)

It is definitely opinionated and influenced by our work...but not designed solely for it.

But, also, we continue to improve. Most notably in the work on Multi-group Raft - https://github.com/ClickHouse/ClickHouse/issues/54172
