Sheryl John commented on OODT-212:
----------------------------------
- Does the wengine-branch have this capability?
- How do we define a failed PGE task? As of now, we have PGE tasks that "runs
successfully" but they still fail to ingest file(s) due to met-extractor
failures and this will affect future tasks in a workflow. Should this be
considered too?
> Rollback capability for Workflows

> Since workflows can involve sequences of PGE-type tasks that can possibly
> fail, and whose failure may invalidate subsequent PGEs that have already been
> processed, it might be good to have a capability for rolling back
> interactions from prior tasks in a workflow. This is a placeholder for future
> patches on that issue.
