Add posibility for a rollback if a step in the ChangeSet execute fails #55

Open mnugter opened 5 years ago

mnugter commented 5 years ago
  1. You should be able to get failed tasks from a ChangeSet.
  2. Rollback must execute the opposite tasks of the original tasks.
  3. Rollback must not trigger automatically but via a separate call
  4. The documentation should expand on this feature and clearly note the risks involved:
    • The rollback might fail as well, potentially causing more problems.
    • Rollback is not guaranteed as it's not a database transaction but a remote (server) call

This will likely be some form of the Saga pattern:
