[jira] [Comment Edited] (ATLAS-1526) update AtlasAttribute with
methods to derive legacy flags isComposite/reverseAttribute
[ https://issues.apache.org/jira/browse/ATLAS-1526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15854586#comment-15854586 ]

------------------------------------------------------------------
[~madhan.neethiraj] - Just want to make you aware that this logic is causing a regression in Atlas (as was the logic before it). In the test model hive_table_v1 (created in BaseResourceIT), the isComposite attribute is now being ignored in the "db" field because there is not a reverse reference associated with it. I'm not sure if that was the intention or not -- but this is definitely a breaking change. The isComposite attribute does not only affect deletion, it also affects creation. With a composite attribute, you can inline referenced entities. This allows a whole containment graph to be created with one call. This is no longer possible for any composite attributes that do not have an associated reverse reference.

> The logic to map legacy attribute flags isComposite/reverseAttribute to its equivalent constraints in the new data model is spread across multiple locations. Consolidating this logic to a single class will make it easier to manage.
