Druid Enables Analytics at Airbnb

There's a similar story of using Druid at Netflix: https://news.ycombinator.com/item?id=22574647

Druid is a very specialized datastore with a niche usage around low-latency analytics under specific pre-set aggregations but it has a lot of moving parts. It also just recently got a beta SQL interface (which translates to the underlying custom JSON API) and isn't as easy to integrate with existing tools (outside of Kafka).

Overall I suggest smaller companies stick to a standard column-oriented data warehouse like Redshift, BigQuery, Snowflake, Clickhouse, MemSQL, etc instead of Druid.
