-----------------------------------

             Summary: Expose new API from CatalogD to EventProcessor
                 Key: IMPALA-10751
                 URL: https://issues.apache.org/jira/browse/IMPALA-10751
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Kishen Das


We plan to manipulate writeIdList for event based fine grained refreshing so we will need a cache to track open txnId and writeId. We store this in CatalogD so that it can remain in memory even EventProcessor is restarted.

We need a Structure like below and expose an API from CatalogD.
{code:java}
Map<Long, List<(String, Long)>> TxnToTableWriteIds{code}
