I think both Pinot and Druid nowadays offer cloud-hosted solutions. Maybe you started early that only ClickHouse had that offering. Is cloud hosting the only reason you guys choose Clickhouse? I am also wondering is it possible to let users choose the data source?
I am curious about the motivation you choose Clickhouse over Apache Pinot, and Apache Druid? It could be helpful for other folks when choosing the OLAP db from one of them.
