> In case of metastore.direct.sql.batch.size > 0, and number of partition names
> or columns in get_aggr_stats_for is bigger than the
> metastore.direct.sql.batch.size, then the
> AggrStats from the call get_aggr_stats_for might have un-merged stats for the
> same column, so the aggregated stats is not correct, which may make CBO
> generate an outdated execution plan.
