Mithun Radhakrishnan commented on HIVE-9674:
--------------------------------------------
Sorry, this patch isn't ready. {{PreDropPartitionEvent}}'s constructor doesn't
take {{Iterable<Partition>}}. Also, {{HiveMetaStore}} should be sending a
single {{PreDropPartitionEvent}}, instead of one per partition. Will update the
patch shortly.
> *DropPartitionEvent should handle partition-sets.

> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.14.0
> Reporter: Mithun Radhakrishnan
> Assignee: Mithun Radhakrishnan
> Attachments: HIVE-9674.1.patch
>
>
> 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}}.
