Speaking from nearly a decade working on BigQuery, and a year working at Firebolt.
- Stability. It OOMS, your CTO mentioned that last week.
- It is not correct. I believe your team is aware of cases in which your very own benchmarks revealed Clickhouse to be incorrect.
- Scale. The distributed plan is broken and I'm not sure Clickhouse even has shuffle.
- SQL. It is very non-standard.
- Knobs. Lots of knobs that are poorly documented. It's unclear which are mandatory. You have to restart for most.
Don't get me wrong, I love open source, and I love what Clickhouse has done. I am not a fan of overselling. There are problems with Clickhouse. Trying to sell it as a superset of the modern CDW is not doing users any favors.
