Apache Druid

Realtime analytics database for event data

About Apache Druid

Apache Druid is a realtime analytical database built for data engineers who need to ingest streaming data and serve low-latency slice-and-dice queries. It provides native Kafka and Kinesis ingestion plus rollup, so teams can build user-facing analytics on fresh event streams batch-only pipelines that lag hours behind. The workflow keeps setup practical for everyday use, with documentation and integrations that fit existing stacks rather than forcing a complete replacement of tools a team already relies on daily.
