ClickHouse is open source it's def not trash for olap and ts

  clickhouse could barely complete a 15 min moving average; last time I checked it required a very slow correlated subquery. That's pretty much where I stopped evaluating it. edit: after looking it up again, looks like that is still the case, and you have have to be fairly limited with cumulative aggregates if you want the keep performance. maybe someday, but as of now, still not very good.
