About this Druid documentation

The Imply distribution of Apache Druid is at the core of the Imply stack. Imply provides interfaces and tools that ease the usability and operation of Apache Druid. Nevertheless, many core concepts and tasks in Imply, such as data ingestion and management, reflect those in Apache Druid as well.

Accordingly, the Druid documentation here partially reproduces the Apache Druid documentation.

It is important to note that documentation here may include references to quickstart files, configuration bundles, or other artifacts that are available only with the Apache Druid distribution, and may not relevant to Imply. For more information about the Apache Druid distribution, see the Apache Druid website.
