> Key: ATLAS-1459
> URL: https://issues.apache.org/jira/browse/ATLAS-1459
> Project: Atlas
> Issue Type: Improvement
> Reporter: David Radley
> Assignee: David Radley
> Fix For: 0.8-incubating
>
>
> Currently Atlas can use mappedFromRef constraint and the refAttribute param
> in an attribute to point to a child type that points back to the parent .
> See 0030-hive-model.json for an example.
> In an operational environment where we want to update these attributes - we
> want the corresponding attribute (related using the constraints) to be
> updated.
> I suggest that we add an inSyncRefAttribute in addition to the existing
> refAttribute. If inSyncRefAttribute constraint is specified then the
> attribute pointed to is kept in sync with our attribute. On creates, updates
> and deletes. This will be supported for List and non List attributes.
