Description

We always say Galera replication is synchronous, but is it really? Always? For every step? What are the caveats of such replication? What does virtual-synchronous mean? In this talk, I'll discuss what certification and group communication are, and how they're performed. I'll also cover the difference between MySQL 5.6 GTID and Galera GTID. The goal of this presentation is to explain how a transaction is replicated using Galera. After this presentation, the audience should be comfortable with terms like "brute force abort," "flow control," "local certification failure," etc. The plan is to demystify Galera technology with easy illustrations and analogies.
