Subject [jira] [Commented] (HIVE-9674) *DropPartitionEvent should handle partition-sets.
Date Wed, 08 Apr 2015 21:55:16 GMT


Mithun Radhakrishnan commented on HIVE-9674:

Actually, [~sushanth], let's hold off for right now, on this one. I'll rebase this under the
assumption that HIVE-9609 is good to go.

> Dropping a set of N partitions from a table currently results in N DropPartitionEvents
(and N PreDropPartitionEvents) being fired serially. This is wasteful, especially so for large
N. It also makes it impossible to even try to run authorization-checks on all partitions in
a batch.
> Taking the cue from HIVE-9609, we should compose an {{Iterable<Partition>}} in
the event, and expose them via an {{Iterator}}.
