> Statistics for table is maintained for all the partitions. The table level
> basic stats present in the table has the combined data for all the
> partitions. When only a few partitions are replicated, the replicated stats
> for the table may not be correct. In case of partition column stats, the
> aggregate stats from the partitions stats table will not correct. So the
> statistics replication can not be supported in case of partition levee
> replication.
> TODO : Need to check how to handle it.
