Zhihua Deng resolved HIVE-27746.
--------------------------------
Fix Version/s: 4.1.0
Resolution: Fixed
Merged to master. Thank you [~hemanth619] , [~jfs] and [~henrib] for the review!
A property: metastore.alterPartitions.notification.v2.enabled is introduced to
ensure backward compatibility when it sets to false, so downstream notification
consumers can still process the ALTER_PARTITION event without changes.
> Hive Metastore should send single AlterPartitionEvent with list of partitions

> Project: Hive
> Issue Type: Improvement

> Fix For: 4.1.0

> In HIVE-3938, work was done to send single AddPartitionEvent for APIs that
> add partitions in bulk. Similarly, we have alter_partitions APIs that alter
> partitions in bulk via a single HMS call. For such events, we should also
> send a single AlterPartitionEvent with a list of partitions in it.
> This would be way more efficient than having to send and process them
> individually.
> This fix will be incompatible with the older clients that expect single
> partition.
