[jira] [Commented] (ATLAS-1419) Entity attribute values are overridden to null when their value is not provided during complete updates

["Sarath Subramanian (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ATLAS-1419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15800437#comment-15800437 ] 

Sarath Subramanian commented on ATLAS-1419:
-------------------------------------------

Updated the patch to include 'null' assignment during update for primitive types, arrays and maps. Previously if you update an attribute to 'null', its ignored and old values are persisted. Fixed in TypedInstanceToGraphMapper.java and DefaultMetadataService.java

Tested the changes using postman, only the attribute specified is updated and the other attribute values are intact in vertex.

> Currently the hooks all use complete entity update APIs which causes values to be overridden if the hook is not able to provide a value for that attribute. For eg: Asset.description value is always set to null. This causes attribute updates to be lost
