Hey, Ofek from Datadog here!
I recently implemented our ClickHouse integration [1], so if any of you would like to try it out we would appreciate feedback. I really enjoyed learning about this database, and it has excellent docs :)
Oh fun fact, speaking of docs, this was the first integration of ours that we scrape docs for as part of the test suite. So when a new built-in metric is added it will fail our CI until we support it [2]. We just did this again for Apache Airflow [3].
