[jira] [Created] (NIFI-3630) FlowFileRepository / WriteAhead Log should use a BufferedOutputStream when checkpointing

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

             Summary: FlowFileRepository / WriteAhead Log should use a BufferedOutputStream when checkpointing
                 Key: NIFI-3630
                 URL: https://issues.apache.org/jira/browse/NIFI-3630
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne
            Assignee: Mark Payne


Currently, calls to MinimalLockingWirteAheadLog's checkpoint() method create a FileOutputStream, then wrap that in a DataOutputStream and start writing to the DataOutputStream, passing that along the SerDe as well. The FileOutputStream that it writes to should be wrapped in a BufferedOutputStream, as each call to checkpoint() is very taxing on the file system currently.
