[jira] [Created] (IMPALA-14534) Batch process events in the TableProcessor queue

Quanlong Huang created IMPALA-14534:
---------------------------------------

             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.
