---------------------------------------
Summary: Batch process events in the TableProcessor queue
Key: IMPALA-14534
URL: https://issues.apache.org/jira/browse/IMPALA-14534
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Reporter: Quanlong Huang
When Hierarchical Event Processing is enabled, events on the same table are
queued in a TableProcessor. We should be able to reload metadata of the table
once to process all events in the queue:
* If there are only partition-level events, reload the relative partitions in
parallel using the existing batch logic.
* If there are table-level events, clean the queue and reload the whole table.
