End Google Ads 201810 - BS.net 01 --> The new MySQL 5.6.5 Development Milestone Release (DMR) introduces a much anticipated feature - Global Transaction Identifiers (GTIDs) for MySQL replication. GTIDs make it simple to track and compare replication progress between the master and slave servers. This enables much simpler recovery from failures of the master, while also introducing great flexibility in the provisioning and on-going management of multi-tier or ring (circular) replication topologies.
