MySQL Group Replication is a recent MySQL plugin that brings together group communication techniques and database replication, providing both a high availability and a multi-master update everywhere replication solution.

High availability is achieved through redundancy, by consistently replicating data throughout a set of MySQL servers. Multi-master update everywhere is based on row-level conflict detection on the fact that the plugin leverages distributed coordination among servers to deploy consistent conflict handling. Thus the system behaves as a replicated state machine. To have all this working together, there is an underlying work of a well-known paradigm in distributed computing: Group Communication and Distributed Consensus - that is becoming quite hot in the software industry nowadays, along with with top-notch software architecture.
