Edward Capriolo commented on HIVE-5158:
---------------------------------------
A thing to keep in mind is that some tables with a huge number of partitions
will OOM a client if you attempt to fetch them all at once. So some support for
paging is required.
> allow getting all partitions for table to also use direct SQL path

> 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.
