Well, to be clear, we haven’t chosen it yet — we’re evaluating it. That said, it is looking quite promising for our use case. The Druid docs say it well: > Druid is an open source data store designed for OLAP queries on event data. And that’s exactly what we need. The other options you listed are excellent systems, but they’re more general than Druid. Because Druid is specifically focused on OLAP queries on event data, it has features and properties that make it very well suited to such use cases. In addition, Druid has built-in support for ingesting events from Kafka topics and making those events available for querying with very low latency. This is very attractive for my use case. If you’d like to learn more about Druid I recommend this talk from last month at Strange Loop: https://www.youtube.com/watch?v=vbH8E0nH2Nw HTH!
