Subject [jira] [Commented] (HIVE-2213) Optimize get_partition_names_ps()
Date Sat, 18 Jun 2011 00:49:47 GMT


Paul Yang commented on HIVE-2213:

If get_partitions_ps_with_auth() was not correct before, then we should fix the method to
produce the correct behavior. Ideally, it should have been done in a separate JIRA, but it
should be okay to include in this one.

+1 looks good though, will test and commit.

> If a table has a large number of partitions, get_partition_names_ps() make take a long
time to execute, because we get all of the partition names from the database.  This is not
very memory efficient, and the operation can be pushed down to the JDO layer without getting
all of the names first.
