> As part of clustering, metadata such as hoodie_commit_time changes for
> records that are clustered. This is specific to
> SparkBulkInsertBasedRunClusteringStrategy implementation. Figure out a way to
> carry commit_time from original record to support incremental queries.
> Also, incremental queries dont work with 'replacecommit' used by clustering
> HUDI-1264. Change incremental query to work for replacecommits created by
> Clustering.
