Performance issue of calculation for the weight for ego net

Question

We have the below Graph Data below. only 5 Vertexes but we have many Edges. How can I handle below Querys?I would like to get the path from one node to one other. I just want to get the cycle path and calculate sum of the weight of the ego. The cycle will be from one to the other and one to itself. And I'd like to filter the sum of the calculation of the weight.

suresh       = graph.addVertex(label,'person','uuid','7bff1bc0-cef1-1033-8f28-d99da6cfd8a9')
robin_niu    = graph.addVertex(label,'person','uuid','e3348740-d37f-1031-8b5b-89fbb6fdad64')
hujunjie     = graph.addVertex(label,'person','uuid','5e5139c0-dbe7-102e-8780-bedba724cbf7')
clintpollitt = graph.addVertex(label,'person','uuid','d92c6340-f98b-1035-85d7-bee5d5cc5ebe')
yanjuqi      = graph.addVertex(label,'person','uuid','2d9fba40-74c7-1033-8e84-d3a6c90ad2e9')

below query can't work very well. How can I fix this issue?

g.V().has('uuid','e3348740-d37f-1031-8b5b-89fbb6fdad64').as('v').
  repeat(outE().as('e').inV().as('v')).
    until(has('uuid','2d9fba40-74c7-1033-8e84-d3a6c90ad2e9')).

         by(union(values('weight'),

Answer 1

This query is going to run forever, as your graph contains cyclic paths, which are not considered by your query. I assume, that you only care about the shortest path (otherwise it wouldn't make much sense to fill up the a collection IMO). A simple change will fix your query:

gremlin> g.V().has('uuid','e3348740-d37f-1031-8b5b-89fbb6fdad64').as('v').
......1>   repeat(outE().as('e').inV().as('v')).
