In episode 76 of Thinking Elixir, we talk with host David Bernheisel about his recently released Safe Ecto Migrations guide. Intended as a resource for the community, it’s a 4-part series covering how Ecto migrations work, running migrations on production, provides a set of common-task recipes and strategies for migrating data in addition to DB structure. We discuss ideas around migrations like avoiding table locks on production, how to safely add DB check constraints, separating data migrations from structure changes, painful learning experiences and much more!
