> 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
> Priority: Major
> Fix For: Impala 4.5.1
>
>
> 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.
