22: Running migrations in production with Patryk Bąk

We talk with Patryk Bąk about running migrations in production. For production systems where downtime or service interruptions are a problem, we sometimes need to take special care when migrating data structures or the data itself. Patryk shares some valuable tips and techniques along with examples of when to use them. We chime in with war stories, our own tips, and mistakes we've made. A great resource when migrating data in your own systems. Check it out!
