---------------------------------
Summary: ReconDBProvider.truncateTable(..) is inefficient
Key: HDDS-15894
URL: https://issues.apache.org/jira/browse/HDDS-15894
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Recon
Reporter: Tsz-wo Sze

The truncateTable(..) method in ReconDBProvider
- indeed is clearing the entire table but not truncating it.
- It uses an iterator to delete the entry one by one, which is very slow.
Better ways suggested by Google are either:
- Method 1: Drop and Recreate (Fastest)
- Method 2: Use deleteRange (For Default or Inline Clearing)
See below for more details.
