                 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: J=C3=B8rgen L=C3=B8land


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