[jira] [Commented] (ATLAS-4048) Entity Creation: Updates to Business Metadata

["Madhan Neethiraj (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ATLAS-4048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17238425#comment-17238425 ] 

Madhan Neethiraj commented on ATLAS-4048:
-----------------------------------------

[~umesh.padashetty] - classifications and business-metadata attributes of an entity are not modified during REST API call to update the entity. Allowing this could cause unintentional removal of classifications and business-metadata - as API client's are likely to deal only with attributes that are known when the client was developed; hence wouldn't know about classifications and business-metadata which could be dynamically added to entities.

Note that if REST API call creates an entity, provided classifications and business-metadata will be assigned to the entity - as there is no risk of removing existing value.

Also, note that import operation replaces classifications and business-metadata on entities with the values specified in the import file. This is an expected behavior.

> *Background*
> Business Metadata attributes provide a simple way to augment attributes to existing entity types.
> Updating Business Metadata for existing entities via REST APIs did not happen as the changes were not tracked when considering entity for update.
> *Steps to Duplicate*
> Setup:
>  * Create Business Metadata and add 3 attributes.
> Steps to duplicate:
>  # Via REST API, create an entity with 3 Business Metadata attributes. 
>  # From the web UI, load the entity where attributes have been added.
>  # Delete 1 attribute.
>  # Use entity update REST API to update the entity from step 1.
> Expected results: Entity will have all 3 attributes.
> Actual result: Entity will contain only 2 attributes that were present in step 2.
>  *Root Cause*
> During entity creation flow, the Business Metadata attributes are not considered when detecting if entity has changes. 
> Solution: Add a step to detect changes to Business Metadata attributes.
