76: Safe Ecto Migrations with David Bernheisel

We talk with host David Bernheisel about his Safe Ecto Migrations guide that was recently released. 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!
