[jira] [Commented] (OODT-212) Rollback capability for Workflows

["Sheryl John (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OODT-212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13218900#comment-13218900 ] 

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?

> 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.
