Henrik Ingo presented on choosing a MySQL replication and high availability solution. He discussed various options like MySQL replication, Tungsten, Galera, DRBD, and NDB. Galera provides synchronous multi-master replication with no single point of failure and supports InnoDB with good performance based on benchmarks. It offers simplicity over more complex clustering frameworks. The presentation evaluated solutions based on usability, performance, and support for features like asynchronous replication and global transaction IDs.
