Druid is a high performance real-time analytics database. Druid's main value add is to reduce time to insight and action.

Druid is designed for workflows where fast queries and ingest really matter. Druid excels at powering UIs, running operational (ad-hoc) queries, or handling high concurrency. Consider Druid as an open source alternative to data warehouses for a variety of use cases. Thedesign documentation explains the key concepts.

You can get started with Druid with ourlocal orDocker quickstart.

Druid provides a rich set of APIs (via HTTP andJDBC) for loading, managing, and querying your data.You can also interact with Druid via the built-inweb console (shown below).

Loadstreaming andbatch data using a point-and-click wizard to guide you through ingestion setup. Monitor one off tasks and ingestion supervisors.

Manage your cluster with ease. Get a view of yourdatasources,segments,ingestion tasks, andservices from one convenient location. All powered bySQL systems tables, allowing you to see the underlying query for each view.

Use the built-in query workbench to prototypeDruidSQL andnative queries or connect one of themany tools that help you make the most out of Druid.
