Description

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).
