Clean up an apache druid cluster

Question

Is there any way to clean up all the druid data (tasks, storage, etc.) for testing purposes?

Found the tutorial which demonstrates the segment deletion:

• https://druid.apache.org/docs/latest/ingestion/data-management.html#delete

And reset-cluster tool:

• https://druid.apache.org/docs/latest/operations/reset-cluster.html

My goal is to have a fresh druid cluster, every time I run testing.

If you are asking which of the two options to use, the reset-cluster tool will address your use case as it has options to remove metadata, task logs and segment data in deep storage. The --all option will remove all of them.

The segment deletion process, on the other hand, is used to remove unwanted segments from the cluster and deep storage, but does not address metadata in general or task logs.
