    No you didn't. They're doing what is often referred as "online schema change" using https://github.com/github/gh-ost (but the concept is the same than percona's pt-online-schema-change, or https://github.com/soundcloud/lhm.

    Is there anything similar for MySQL? There is https://github.com/soundcloud/lhm but it's pretty much outdated nowadays
  • Do you use migrations for data manipulations? What are the pro's and con's ?

    I may do it from the console or a task if I wanted to modify a large number of records, e.g. something in my Users table. I think you need a sense of how long the update will take - I'm not sure if there's any issue with migrations timing out or such like. If I modify my Users schema it takes 5 minutes or so as it has to make a copy of the table and swap it in and that works fine - https://github.com/soundcloud/lhm
