             Summary: Handle transient tables that get recreated multiple times during pruning
                 Key: TEPHRA-254
                 URL: https://issues.apache.org/jira/browse/TEPHRA-254
             Project: Tephra
          Issue Type: Bug
            Reporter: Poorna Chandra
            Assignee: Poorna Chandra


TEPHRA-244 handles temporary tables during pruning by removing regions of deleted tables when
computing prune upper bound. This ensures that transient tables do not block pruning. 

However, if a transient table is created/deleted again with the same name and never gets a
chance to be compacted, then it has a potential to block pruning. 

One way to handle this would be to keep track of creation time for every table and use that
information to remove regions of previous iterations of a transient table.
