> clean up old stats and re-build new one
> -----------------------------------------------------------------------------------------------------------------
>
> Key: HUDI-8662
> URL: https://issues.apache.org/jira/browse/HUDI-8662
> Project: Apache Hudi
> Issue Type: Sub-task
> Reporter: sivabalan narayanan
> Assignee: sivabalan narayanan
> Priority: Critical
> Fix For: 1.0.1
>
>
> As of now, we do not store the list of cols we index anywhere.
> so, if user chose colA, colB for 100 commits. and then switches to colC, colD
> after 100th commit, we will go ahead and keep generating stats for just for
> colC and colD.
>
> We have plans to store cols being indexed
> https://issues.apache.org/jira/browse/HUDI-8232,
>
> So, we can leverage that to tear down existing one and re-build col stats
> from scratch for colC and colD.
