[jira] [Created] (IMPALA-14074) Support metadata cache warmup of some tables in catalogd startup

Quanlong Huang created IMPALA-14074:
---------------------------------------

             Summary: Support metadata cache warmup of some tables in catalogd startup
                 Key: IMPALA-14074
                 URL: https://issues.apache.org/jira/browse/IMPALA-14074
             Project: IMPALA
          Issue Type: New Feature
          Components: Catalog
            Reporter: Quanlong Huang


Users might want to warm up the metadata cache for some important tables after restarting catalogd. We can provide a configuration file loaded in catalogd startup that contains one table at a line. Catalogd triggers metadata loading of those tables in the background. Then users don't need to explictly run some queries to warm up the cache.
