Experience level: 
50 minutes conference
Case Stories
Tools and Techniques


This talk explains why Dropbox considered rolling out global transaction IDs so early. Additionally we discuss the steps involved in deploying such a change across a large fleet, the challenges faced, open issues, and lessons learned during the migration. Overview: o Cluster management o The most common topologies are described and the issues with each are explored as well as Dropbox's replication topology and the reasons we chose it. o How MySQL replication works o Details of the replication flow are explained to help understand why moving to GTIDs is so compelling. o Positional vs GTIDS replication o Both replication architectures are compared, advantages and disadvantages with regard to cluster management as well as backup and recovery. o Roll out o The steps taken to roll out global transaction ids. We didn't do this alone. We reached out to and Facebook for input as well as leveraged our relationship with Percona to ensure as smooth a transition as possible. o Issues o All the bumps and bruises we met as we moved from positional to gtid replication. o Where we are now o An update on our environment since we rolled out GTIDs. If you missed this talk at Oracle Openworld here's a second chance.
