Replication latest features: the community sceptic roundup

Replication latest features: the community sceptic roundup

 26 April - 11:10 AM - 12:00 PM @ Ballroom A
Experience level: 
50 minutes conference


Replication in the last years has been a game of marketing and bragging, where features have been presented as life-changing and highly innovative. Sometimes, these features are really good, and meet the users expectations. Some other times, though, the features are just an item on a completeness list, and it's difficult to understand what is good and what is bad. This talk analyses the newest replication features in MySQL and MariaDB, and shows how they work in practice, with the good parts, and especially the bad ones highlighted and explained with examples. The talk covers: * Replication monitoring; * Global Transaction Identifiers; * Multi-source replication; * Parallel appliers; * Group replication; * Replication safety. For each feature, there is an explanation of how it is implemented in various flavors and a live demo of the important points. The theme of the talk is "how can I be in control of the replication stream if I start using this new feature?" And so we'll see what new advantages and challenges are there when adding GTID to regular replication. And what happens when we also want to add multi-source data streams and parallel appliers. Attendees will learn the basic of monitoring, and how to apply them to all the features mentioned above. They will walk away with an understanding of the features and how well they compare to each other.
