[jira] [Created] (OMID-129) Omid VisibilityFilter should cache uncommitted transactions

Yonatan Gottesman created OMID-129:
--------------------------------------

             Summary: Omid VisibilityFilter should cache uncommitted transactions
                 Key: OMID-129
                 URL: https://issues.apache.org/jira/browse/OMID-129
             Project: Apache Omid
          Issue Type: Improvement
            Reporter: Yonatan Gottesman
            Assignee: Yonatan Gottesman


When the TransactionVisibilityFilterBase encounters a cell of an uncommitted transaction, store that starts TS in the commit cache with commit timestamp Long.MAX_VALUE.

With this cache when scanning through lots of uncommitted values omid wont have to go to the commit table for every cell.
