---------------------------------
Fix Version/s: (was: 1.0.0)
> Change the rollback mechanism for MDT to actual rollbacks rather than
> appending revert blocks
> ---------------------------------------------------------------------------------------------
>
> Key: HUDI-6153
> URL: https://issues.apache.org/jira/browse/HUDI-6153
> Project: Apache Hudi
> Issue Type: Improvement
> Components: metadata
> Reporter: Prashant Wason
> Assignee: Prashant Wason
> Priority: Major
> Fix For: 0.14.0
>
>
> When rolling back completed commits for indexes like record-index, the list
> of all keys removed from the dataset is required. This information cannot be
> available during rollback processing in MDT since the files have already been
> deleted during the rollback inflight processing.
> Hence, the current MDT rollback mechanism of adding -files, -col_stats
> entries does not work for record index.
> This PR changes the rollback mechanism to actually rollback deltacommits on
> the MDT. This makes the rollback handing faster and keeps the MDT in sync
> with dataset.
