Is this similar to Apache Drill[0]/Google Dremel[1] (BigQuery[2])? One differences is that it seems to be able to do mutations to data, not simple appends.

Yes, it is similar to BigQuery with a couple of differences as you pointed out. The big ones being that it's fully open source and self-hostable.

It's less similar to Apache Drill - Drill is "only" a query engine and doesn't handle the actual data storage. EventQL combines a bigtable-like storage engine (optimized for the analytics use case) with a dremel/bigquery/dremel-like query engine.

How does it compare to Clickhouse, recently released from Yandex [0]?

Awesome! Thanks! I'll have to try it out.
