Sub-Second Queries

Druid supports fast aggregations and sub-second OLAP queries. Druid is designed for multi-tenancy and is ideal for powering user-facing analytic applications.

Real-time Streams

Druid supports streaming data ingestion and offers insights on events immediately after they occur. Retain events indefinitely and unify real-time and historical views.

Scalable to Petabytes

Existing Druid clusters have scaled to petabytes of data and trillions of events, ingesting millions of events every second. Druid is extremely cost effective, even at scale.
