> Key: HUDI-3954
> URL: https://issues.apache.org/jira/browse/HUDI-3954
> Project: Apache Hudi
> Issue Type: Improvement
> Components: cleaning
> Reporter: 董可伦
> Assignee: sivabalan narayanan
> Priority: Critical
> Labels: pull-request-available
> Fix For: 0.12.1
>
>
> Don't keep the last commit before the earliest commit to retain
> According to the document of {{{}hoodie.cleaner.commits.retained{}}}:
> Number of commits to retain, without cleaning. This will be retained for num_of_commits * time_between_commits (scheduled). This also directly translates into how much data retention the table supports for incremental queries.
>
> We only need to keep the number of commit configured through parameters {{{}hoodie.cleaner.commits.retained{}}}.
> And the commit retained by clean is completed.This ensures that “This will be retained for num_of_commits * time_between_commits” in the document.
> So we don't need to keep the last commit before the earliest commit to retain,If we want to keep more versions, we can increase the parameters {{hoodie.cleaner.commits.retained}}
