org.apache.derby.iapi.store.replication.master.MasterFactory
This is the interface for the replication master controller service. The master controller service is booted when this instance of Derby will have the replication master role for this database.

The replication master service is responsible for managing all replication related functionality on the master side of replication. This includes connecting to the slave, setting up a log buffer to temporarily store log records from the LogFactory, and to ship these log records to the slave.

The master controller currently only supports asynchronous replication. This means that there are no guarantees that transactions that have committed here (the master side) are also reflected on the slave side. However, the slave version of the database IS guaranteed to be transaction consistent. This implies that:
- A transaction t that is committed on the master will either be fully reflected or not be reflected at all on the slave when the slave database is turned into a non-replicated database (that is, at failover time)
- Slave execution of operations is in the same serial order as on the master because replication is based on redoing log records to the slave. By definition, log records are in serial order. This implies that if transaction t1 commits before t2 on the master, and t2 has been committed on the slave, t1 is also guaranteed to have committed on the slave.
