Adar Dembo created KUDU-2055:
--------------------------------

             Summary: Coalesce hole punching when deleting groups of blocks
                 Key: KUDU-2055
                 URL: https://issues.apache.org/jira/browse/KUDU-2055
             Project: Kudu
          Issue Type: Bug
          Components: fs
    Affects Versions: 1.4.0
            Reporter: Adar Dembo


We should implement hole punch coalescing in the log block manager. I'm not sure whether it'll be faster than per-block hole punching, but it should definitely be no worse than what we do today (and it will definitely reduce the number of syscalls).

To do this we need awareness within the LBM of when we're deleting groups of blocks, which should come through KUDU-1943.
