             Summary: Improve performance when deleting classification from 
'TRAIT_NAMES_PROPERTY_KEY' and 'PROPAGATED_TRAIT_NAMES_PROPERTY_KEY'
                 Key: ATLAS-3778
                 URL: https://issues.apache.org/jira/browse/ATLAS-3778
             Project: Atlas
          Issue Type: Improvement
            Reporter: Sarath Subramanian


When deleting a classification, we remove the following properties from entity 
vertex and update these properties with the classification name removed.
 * *PROPAGATED_TRAIT_NAMES_PROPERTY_KEY*
 * *TRAIT_NAMES_PROPERTY_KEY*

This will be an expensive operation during commit time when dealing with large 
number of classifications. This improvement will only remove the deleted 
classification name from both the above property keys and the commit foot print 
will be less.
