[the-other-tim-brown]

Change Logs

For files that are not created by Hudi but added to the table (zero copy bootstrap or OneTable case) we are unable to remove the column stats after these files are removed from the table view.

Impact

Allows proper cleanup of metadata table's stats partition

Risk level (write none, low medium or high below)

None

Documentation Update

Describe any necessary documentation update if there is any new feature, config, or user-facing change

• The config description must be updated if new configs are added or the default value of the configs are changed
• Any new feature or user-facing change requires updating the Hudi website. Please create a Jira ticket, attach the ticket number here and follow the instruction to make changes to the website.
