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 will implement write set extracting and applying functionality inside MySQL/innodb server making use of . It will use an external replication engine for transferring the write sets and interface with the replication engine happens through function calls and callbacks defined in wsrep API.

Galera library will be compliant with wsrep API and our future MySQL/Galera development and testing will all be based on wsrep deliverables.

We will also implement open source replication for wsrep API. This project will most likely be called openrep and will implement single master fully synchronous replication.
