Mithun Radhakrishnan updated HIVE-3938:
---------------------------------------
Attachment: Hive-3938-Support_for_Multi-table-insert.patch
Modified AddPartitionEvent to support multi-table-insert. Partitions added to
multiple-tables atomically are now specified in the same event.
I've also combined the changes to HCatalog-609 herewith (since we're in the
same code-base). HCatalog's NotificationListener continues to notify only
per-table events. So each AddPartitionEvent has potential to launch multiple
JMS Notifications, with multi-table inserts.
> Hive MetaStore should send a single AddPartitionEvent for atomically added
> partition-set.

> HiveMetaStore::add_partitions() currently adds all partitions specified in
> one call using a single meta-store transaction. This acts correctly. However,
> there's one AddPartitionEvent created per partition specified.
> Ideally, the set of partitions added atomically can be communicated using a
> single AddPartitionEvent, such that they are consumed together.
> I'll post a patch that does this.
