Hi Amiya, I saw that but wasn't quite sure the intent given the example. It talks about edge labels but the examples are vertices & values?
g.V(h).out('mother') -> returns a vertex traversal? g.V(h).values('age') -> returns a Value?
Also, what do you mean by 'But if you have a high cardinality for a single edge type, then you have to manually create edge index on respective property.'?
