>          Issue Type: Improvement
>          Components:  atlas-core
>    Affects Versions: 2.0.0
>            Reporter: Sarath Subramanian
>            Assignee: Sarath Subramanian
>            Priority: Major
>             Fix For: 2.1.0

> 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.
