Automating Schema Changes using gh-ost

Tom Krouper GitHub delivers his talk Automating Schema Changes using gh-ost on DAY 3 of the Percona Live Open Source Database Conference 2017 427 at Santa Clara CA. GitHub has been using gh-ost for online schema migrations since before it was open sourced in August of 2016.
Once gh-ost was in place helping our migrations run more smoothly the Database Engineers didnt want to have to be involved in running them anymore. In this session well discuss the steps we took to remove humans from most of the steps of running a migration.
This includes implementing chatops with Hubot leveraging the existing CI to check schema differences and writing scripts that verify a successful migration.
