Baleen Migrations

Baleen Migrations is a project that seeks to abstract the domain of performing migrations of any kind into a single independent package. Its goal is to excel at one single task: provide an intuitive, well-tested framework to migrate “something” from point A to point B (or vice-versa if going down).

In other words, we take care of WHICH migrations are run and the mechanism to run them. Everything else is the responsibility of the implementation:

  • WHAT is going to be migrated? It could be a database, images, documents, etc.
  • HOW its going to be migrated? You can wrap each migration into DB transactions. Or not, its up to you.
  • What to do when a migration fails? We’ll let you know WHEN it happens, but its up to you to decide what to do (e.g. cancel the transaction / re-throw the exception, etc).
