Frédéric Descamps (Oracle) delivers the talk, "MySQL Group Replication: The Magic Explained v2", on DAY 2 of the Percona Live Open Source Database Conference 2019, 5/30, at Austin, TX.

During this talk, I explain how Group Replication replication works.

This is a theoretical talk in which I explain in details what replication is and how it works.
I discuss what certification is and how it's done. What is XCOM and GCS?

Is Group Replication synchronous? What are the four new consistency guarantees and how do they work?

What is the benefit of Single Primary Mode?

What are the caveats of such replication?

Why is Paxos Mencius more efficient than Totem? Is it always?

IPV4 and what about IPV6

After this presentation, the audience should be comfortable with the technical terms and understand how it works.

Don't miss this talk, the magician will reveal his tricks!
