> The derby instance that has the slave role for a database 'x' has to redo log records
sent from the master. These log records are sent in chunks as a byte[]. To be useful to the
slave, these chunks of log records must be parsed into individual log records. 
> The actual format of the received log record chunks is defined by the replication log
buffer (see DERBY-2926).
