Subject [jira] [Commented] (ATLAS-2523) Import relationship, preserving existing GUID
Date Thu, 03 May 2018 16:32:00 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-2523?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16462728#comment-16462728

Ashutosh Mestry commented on ATLAS-2523:
----------------------------------------

Thanks [~grahamwallis] for the details. I get a better understanding of your intent. This
patch is fine as it is. I may have to make a small change at another place where I am assigning
GUID to an entity that is being imported since this patch will make it redundant (not harmful). 

It may be wroth removing these lines as I think it will make the code cleaner.

These are the lines that I will have to remove:

_EntityGraphMapper: line 762_ 

<code>

// for import use the relationship guid provided
if (context.isImport()) {
    String relationshipGuid = getRelationshipGuid(ctx.getValue());
    if(!StringUtils.isEmpty(relationshipGuid)) {
    AtlasGraphUtilsV1.setProperty(ret, Constants.RELATIONSHIP_GUID_PROPERTY_KEY, relationshipGuid);
    }
}

</code>

> To add a relationship defined externally (in another metadata repository), I want to
be able to add the relationship and maintain the existing GUID.
> This is possible for an entity by performing an import. It does not seem to be possible
for relationships., because the relationship store always generates a new GUID, which overwrites
the existing GUID.
