> While handling create/update of relationship instances, lookup to retrieve vertex of
end-point entities is performed multiple times. This overhead can be avoided by updating the
flow to pass the vertices retrieved earlier.
> Also, entity update operation compares existing attribute values with incoming values
- to determine if update call indeed makes any changes at all. This comparison can be improved
by having AtlasType support operation areEqualValues(Object val1, Object val2).
