I'd go for Druid + Pivot (or BigQuery if you happen to be in GCloud already).

Have you actually deployed this in production? Last year, we had lots of issue with Druid. Do you know about clickhouse?

can you write briefly about the issues you had with Druid? We've been looking at bringing it into out stack for our OLAP queries and aggregates and would appreciate a war story.
