----------------------------------------------
Summary: Enable event processor to consume ALTER_PARTITIONS events
from metastore
Key: IMPALA-13593
URL: https://issues.apache.org/jira/browse/IMPALA-13593
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Reporter: Sai Hemanth Gantasala
Assignee: Sai Hemanth Gantasala
HIVE-27746 introduced emitting ALTER_PARTIONS events which contain all the
partition names involved in the alter event. Before this metastore emits one
ALTER_PARTITION event for a single partition, so for a table having huge
partition count Impala would have to process a ton of alter_partition events.
Instead, we can now consume single ALTER_PARTITIONS events and then refresh
metadata for those partitions in the CatalogD's cache.
