On top of being a really good OLAP database, what has been a game changer for me is the built-in connectors for bringing in data from remote sources. It can manage automatic recurring import of a s3 folder containing parquet/json files and it can also connect directly to Postgres. For our data warehouse at a medium sized newspaper, we switched from Druid+postgres+trino to just one big clickhouse node and I’ve never looked back. Much more performant, practical, and a lot less maintenance.
