    Isn't there a need for "removeReverseReference()" - to update the reverseAttribute when a referred entity is deleted? For example: when a hive_column entity is deleted, hive_table.columns needs to be updated.
    
    Perhaps this is already handled in the current implementation. If so, please ignore this comment.

This is already handled in DeleteHandler.deleteEdge().  Also this review request had been discarded a few days ago, so that I could separate the V1 and V2 changes.  If you have any further review comments on the V1 changes, please post them to https://reviews.apache.org/r/56287/
