ashutoshc has requested changes to the revision "HIVE-5158 [jira] allow getting all partitions for table to also use direct SQL path".

  Question on supporting max.

INLINE COMMENTS
  metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java:1387 Seems like its not hard to support max in this scenario. We can simply do  query.setRange(0, max) for it. Did you consider supporting it?

> While testing some queries I noticed that getPartitions can be very slow (which happens e.g. in non-strict mode with no partition column filter); with a table with many partitions it can take 10-12s easily. SQL perf path can also be used for this path.
