+## Multi-stage query task engine
The `druid-multi-stage-query` extension adds a multi-stage query (MSQ) task engine that executes SQL statements as batch
tasks in the indexing service, which execute on [Middle Managers](../design/architecture.md#druid-services).

transformation: creating new tables based on queries of other tables.
