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.
At its core is a set of group communication primitives that act as the building blocks to create reliable, consistent and dependable messaging between the servers in the group. This allows the set of MySQL servers to coordinate themselves and act as a consistent and replicated state machine - in which transactions commit in the same order on every server. As a consequence, the group itself is fault-tolerant, and so is the service provided by the group - the MySQL database service.
In addition to HA, the plugin provides multi-master update everywhere with row-level conflict detection. This builds on the fact that the servers in the group have to agree on how to progress the replicated state machine and so also check for conflicts.
Come and learn about the technical details of the exciting and popular MySQL Group Replication plugin and discuss how this fits in the overall picture of MySQL HA solutions.
