Replication: Add a log buffer for log records that should be shipped to the slave
---------------------------------------------------------------------------------

                 Key: DERBY-2926
                 URL: https://issues.apache.org/jira/browse/DERBY-2926
             Project: Derby
          Issue Type: Sub-task
          Components: Store
    Affects Versions: 10.4.0.0
            Reporter: Jørgen Løland


When a Derby instance has the master role for a database, log records are shipped to the slave
to keep it up to date. A buffer is needed because the log records should not be shipped one
at a time. Also, writing the log records to a buffer instead of sending them immediately removes
the network communication from the critical path for the transaction.
