At this moment I cannot really understand why someone wouldn't use ClickHouse for OLAP. Beyond my success experience with it in production, I'm currently testing it with data that for historical or commercial reasons was always sitting in BigQuery and the results are really fantastic. I don't think Druid can compare to it at all.

As of 2 years ago, ClickHouse did not have as-of joins, which was a dealbreaker for me.

(Non is the usual suspects do either... I eventually used pandas+dask)

Cannot compare in a sense that ClickHouse is superior?
