The Replicator is designed to include a number of specialized features designed to improve its usefulness for particular problems like availability.
* Replicated changes have transaction IDs and are stored in a transaction history log that is identical for each server. This feature allows masters and slaves to exchange roles easily.
* Smooth procedures for planned and unplanned failover.
* Built-in consistency check tables and events allow users to check consistency between tables without stopping replication or applications.
* Support for statement as well as row replication.
* Hooks to allow data transformations when replicating between different database types.
