--------------------------------------------
Summary: Improve ALTER_PARTITIONS event message
Key: HIVE-29141
URL: https://issues.apache.org/jira/browse/HIVE-29141
Project: Hive
Issue Type: Improvement
Components: Standalone Metastore
Reporter: Sai Hemanth Gantasala
Assignee: Sai Hemanth Gantasala
Before HIVE-27746, AlterPartitionMessage used to have beforePartition and
afterPartition, by looking at both the objects, clients like Impala will
determine what really changed in AlterPartitionEvent and decide whether to
update table metadata, file metadata e.t.c.
After HIVE-27746, AlterPartitionsMessage now only has afterParitions objects.
So Impala now has no way to determine what really changed in partitions. It
would be nice for HMS to help determine what changed by:
1) Maybe precompute the partitions that really changed and append the names of
the partition names in the event message (OR)
2) Add a flag in the event message indicating that the particular partition
needs to be refreshed in Impala's cache.
