CQL query timeout issues
Also, if the latencies come from reading back the edges, sometimes building a vertex centric index helps: https://docs.janusgraph.org/schema/index-management/index-performance/

if this helps with insertions, might be worth looking into that more.

To experiment and check if this is due to lock, you can turn this configuration on:

CQL query timeout issues
Normally, during edge addition, JanusGraph doesn't read all edges back. Maybe worth checking your Cassandra consistency level, if it cross DC QUORUM, that might be expensive to get a lock when edge is being added.

CQL query timeout issues
Hi @HailDevil ! I think having more context might be helpful. Are you using JanusGraphs APIs directly to operate with the edges or you are using Gremlin sever? From my experience, we have some usecases in PROD with 1 million edges between verticies and we don't observe timeouts.
