Automatic File Replication (AFR) is the synchronous replication module (translator) used in Gluster. This talk gives a brief introduction to how AFR works in Gluster and its associated quirks, and then dives into the recent features/ improvements that have been made in this translator, namely:
1. The server and client side split-brain resolution commands that make it a breeze to resolve files that are in split-brain.
2. The 'arbiter' configuration for replica 3 volumes that prevent split-brain altogether.

4. Improvements in self-heal performance.
