Subject [jira] [Commented] (ATLAS-1690) Introduce top level relationships
Date Tue, 26 Sep 2017 15:54:00 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-1690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16180979#comment-16180979

David Radley commented on ATLAS-1690:
-------------------------------------

[~ppadovani] In the master branch, we have added the new RelationshipDefs,[~sarath.kum4r@gmail.com]
has added support for relationship instances, there is an active Jira adding update and delete
support. There is an ongoing Jira relating to the implementation of relationship  tagPropagation.
Some work has been done to add tagPropagation to the existing Hadoop models, using relationshipDef
type definitions; this is a way to get tag propagation with the legacy reference attributes.
You need to move to the new cleaner relationships to get aggregation and many to many support.

I am not aware of any enhancements in the lineage area regarding relationships - I suggest
you raise all the issues that you see as Jiras and we will have a look at them. 

Please raise as Jiras any issues/ regressions that you are seeing as 'a bit unstable', so
we can fix them.
