I like it. Will make that change.
> Update REST endpoints to support eventually consistent UI updates

> Key: METRON-1771
> URL: https://issues.apache.org/jira/browse/METRON-1771
> Project: Metron
> Issue Type: Improvement
> Reporter: Ryan Merriman
> Priority: Major
>
> Currently the REST endpoints that perform document updates either return
> true/false or nothing. This puts the responsibility of retrieving the
> updated state of the object on the client in a separate call or
> optimistically applying the changes and reverting when an update fails. This
> can be problematic if a client attempts to get the current state immediately
> after an update and the change isn't visible yet in the back end.
> Ideally they should return the updated state of the object, eliminating the
> need to look up the updated state in a separate call.
