PoC: Using a Group Communication System (Isis2) to improve MySQL Replication HA

Modern NoSQL solutions make good, old MySQL Replication appear weak on High Availability (HA). Basically, MySQL users have three choices for MySQL Replication HA: give up on HA, believe that doubling single points of failures means HA, or go for a proper but complex solution. Albeit, as NoSQL world and competition proves, solid HA can be dead simple: embed a Group Communication System (GCS) into MySQL! No single point of failure and near zero client deployment is doable. In parts, the proposal surpassed Pacemaker/Corosync. Read on: story, slides, experimental code.

MySQL Replication: Self-Healing Recovery with GTIDs and MySQL Utilities

MySQL 5.6 includes a host of enhancements to replication, enabling DevOps teams to reliably scale-out their MySQL infrastructure across commodity hardware, on-premise or in the cloud.

One of the most significant enhancements is the introduction of Global Transaction Identifiers (GTIDs) where the primary development motivation was:

- enabling seamless failover or switchover from a replication master to slave

- promoting that slave to the new master

- without manual intervention and with minimal service disruption.

You can download the new MySQL Replication High Availability Guide to learn more. …
