Built-in MySQL Replication is known for its capability to enable to scale reads easily. However, there are some limitations and known issues with this solution because of the asynchronous nature of this replication. This talk will describe another way of doing MySQL replication, by using synchronous replication, available in Percona XtraDB Cluster. The open source solution will be explained and compared to traditional asynchronous MySQL replication, as well as some known use cases will be described. Percona XtraDB Cluster is an, open source, high availability and high scalability solution for MySQL clustering. Features include: Synchronous replication, Multi-master replication support, Parallel replication, Automatic node provisioning.
