Description

In cluster deployments it was observed that block deletion can be slow. For example if a user writes a million keys in Ozone, the time it takes for those million keys to be deleted from datanodes can be high. The jira would cover various improvements which can be made for better deletion speeds.

Sub-Tasks

• Datanode should have deletion service thread per volume: Open
