Replication API Project
MySQL Write Set Replication (MySQL-wsrep) is an open source project, which we started in launchpad site: https://launchpad.net/codership-mysql
MySQL-wsrep project implements write set extracting and applying functionality inside MySQL/InnoDB server . It uses an external replication plugin for transferring the write sets and the interface between MySQL server and the replication engine happens through function calls and callbacks defined in wsrep API.
Galera library will be compliant with wsrep API and our future Galera Cluster development and testing will all be based on wsrep deliverables.
