How to use MySQL Global Transaction IDs (GTIDs) in productionStephane Combaudon
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 are also changing a lot of things in how we can perform operations on replication. For instance, skipping transactions is a bit more difficult. Or you can get bitten by errant transactions, a concept that did not exist before.
This is why I will be presenting a webinar on Aug. 27 at 10 a.m. PDT: Using MySQL Global Transaction IDs in Production.
You will learn what you need to operate a replication cluster using GTIDs: how to monitor replication status or to recover from replication errors, tools that can help you and tools that you should avoid and also the main issues that can occur with GTIDs.
This webinar is free but you can register today to reserve your seat. And a recording will be available afterwards. See you next week!
