> By default, Hive collects stats when running operations like alter table
> partition(s), create table, and create external table. However, collecting
> stats requires Metastore lists all files under the table directory and the
> file listing operation can be very expensive particularly on filesystems like
> S3.
> HIVE-18743 made DO_NOT_UPDATE_STATS table property could be selectively
> prevent stats collection.
> This Jira aims at introducing DO_NOT_UPDATE_STATS table property into the
> MetaStoreUtils.updatePartitionStatsFast. By adding this, user can be
> selectively prevent stats collection when doing alter table partition(s)
> operation at table level. For example, set 'Alter Table S3_Table set
> tblproperties('DO_NOT_UPDATE_STATS'='TRUE');' MetaStore will not collect
> stats for the specified S3_Table when alter table add partition(key1=val1,
> key2=val2);
