Apache Druid (incubating) is a high performance analytics data store for event-driven data. It is optimized for sub-second queries to slice-and-dice, drill down, search, filter, and aggregate this data. The most common use case for Druid is powering interactive applications where performance, concurrency, and uptime are important.
Druid was initially created to power a scalable, visual, multi-tenant application where users could not only rapidly slice and dice data to create ad-hoc reports, but also interactively explore data to quickly determine the root cause of patterns and anomalies. It is designed from the ground up for sub-second queries, which are critical in interactive applications
This group is dedicated to bringing together users and developers of Druid to exchange knowledge, insight, and spur the adoption of Druid for innovative research and commercial applications.
