+1 Vote Up -0Vote Down

Thank you to all of you who attended my webinar last week about Global Transaction IDs (GTIDs), which were introduced in MySQL 5.6 to make the reconfiguration of replication straightforward. If you missed my webinar, you can still listen to the recording and download the sides …

How to use MySQL Global Transaction IDs (GTIDs) in production
+1 Vote Up -0Vote Down

Reconfiguring replication has always been a challenge with MySQL. Each time the replication topology has to be changed, the process is tedious and error-prone because finding the correct binlog position is not straightforward at all. Global Transaction IDs (GTIDs) introduced in MySQL 5.6 aim at solving this annoying issue.

The idea is quite simple: each transaction is associated with a unique identifier shared by all servers in a given replication topology. Now reconfiguring replication is easy as the correct binlog position can be automatically calculated by the server.

Awesome? Yes it is! However GTIDs …

Employee +6 Vote Up -0Vote Down

The goal of this post is twofold: (i) to show the power of GTIDs and MySQL 5.6 replication infrastructure in general; and (ii) show MySQL users a way to hack multi-source replication rather painlessly and rather quickly on top of MySQL 5.6 when using the new MySQL 5.6 replication features.Multi-source ReplicationMulti-source replication is often regarded as a mean to aggregate, consolidate, different streams of data into one single server instance, a sink. In many cases the following assumptions hold:

MySQL Replication: Self-Healing Recovery with GTIDs and MySQL Utilities
Employee_Team +2 Vote Up -0Vote Down

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 …
