Re: How to improve traversal query performance
Hi Manabu,
What edge are present between vertices A,B,C,D,E,F?
If there are only edges A-B, A-C, A-D, A-E, A-F, you do not need repeat().
Best wishes, Marc

Re: How to improve traversal query performance
Hi Manabu,
repeat()/simplePath()/emit() can have valid uses, although normally you combine it with the times() or until() step to limit the number of repeats. The profile from your query suggests that

SimplePath query is slower in 6 node vs 3 node Cassandra cluster
Hello,
I am currently using Janusgraph version 0.5.2. I have a graph with about 18 million vertices and 25 million edges.

Re: How to improve traversal query performance
Hi Marc,
Thank you for your reply.
I'm reading ref docs that you referred about sack()/barrier(). But, I've not able to understand yet.
One question.
What means this you advised?
