[jira] [Created] (IMPALA-6557) Show details of recent topic delta update

Juan Yu created IMPALA-6557:
-------------------------------

             Summary: Show details of recent topic delta update
                 Key: IMPALA-6557
                 URL: https://issues.apache.org/jira/browse/IMPALA-6557
             Project: IMPALA
          Issue Type: Improvement
          Components: Catalog
            Reporter: Juan Yu


Details of metadata topic delta updates are very useful for troubleshooting. 

E.g. Num of tables and list of tables in recent topic updates help us know if there are many  tables being updated concurrently.

Are several large tables often updated together?

Are catalog cache version much higher than coordinator cache version?
