[jira] [Created] (KUDU-1726) Avoid fsync-per-block in tablet copy

Mike Percy created KUDU-1726:
--------------------------------

             Summary: Avoid fsync-per-block in tablet copy
                 Key: KUDU-1726
                 URL: https://issues.apache.org/jira/browse/KUDU-1726
             Project: Kudu
          Issue Type: Bug
          Components: tablet
            Reporter: Mike Percy


We should be able to do a full tablet copy, keeping in mind which blocks and WAL segments have changed, and then do a bulk sync-to-disk once the full operation is complete. This would allow the kernel to schedule the IO at its leisure until durability is actually required.

This will likely require changes from the BlockManger API and LogBlockManager implementation to support.
