Hi All, I am running SparkGraphComputer using tinker-pop library on Yarn. I am able to run vertex program successfully and write final output to a mount location. But I a want to make program to write

Hi Joe, You do not describe whether breaking this rule of thumb causes real performance issues in your case. Anyway, JanusGraph allows you to partition the stored edges of a node, see:

I've noticed that the max partition size on Cassandra can get extremely large if you have a node with lots of edges.  The max partition size on the edgestore table on a graph I'm working on is over

Thank you Kevin and Boxuan for the help on this. I was scratching my head on this and decided to blow away the graph and try again. Every-time, I built a small graph and exported to

Hi Joe, > The java code talks directly to cassandra via the Janusgraph library. Should I be using a Gremlin server instead? I see, so you are using embedded JanusGraph. It has less overhead compared

Hi Joe, I just wanted to check a few things: 1. Did you happen to enable `storage.batch-loading`? See https://docs.janusgraph.org/operations/bulk-loading/#batch-loading 2. IIRC you are using

Joe, See https://groups.google.com/g/janusgraph-users/c/foaqfG-MB5E/m/tsNnkhPtBwAJ for a discussion on perhaps the same issue you are running into. Long story short, it appears you have a unique

Hi all - I'm seeing this from a recent graph I built: gremlin> :> g.V(4162).valueMap() ==>{source=[DS_106], sourceName=[GDELTRecord3]} gremlin> :> g.V(4146).valueMap() ==>{source=[DS_106],

Hi Boxuan - Cluster is a 15 node cassandra cluster: nodetool status Datacenter: datacenter1 ======================= Status=Up/Down |/

Gotcha. The recommended way is to use TinkerPop API to do CRUD operations, i.e. GraphTraversalSource.addV() is recommended as it is considered the “standard” way. The `addV` method inherently

Your Cassandra statistics shows pretty low latency, so the problem does not seem to be related to Cassandra. I would check if it’s a network problem. It might also be helpful if you could provide

One thing of note is the tablehistogram for the graphindex table: nodetool tablehistograms graphsource.graphindex graphsource/graphindex histograms Percentile Read

I suspect this is an issue with gremlin java-driver. I just reported here: https://issues.apache.org/jira/browse/TINKERPOP-2766 I believe you should provide all hostnames for now. Best regards, Boxuan

Thank you Boxuan - the code (REST service) that is modifying the graph is being called continuously when running. A slow example looks like this: Metrics: Traversal Metrics Step

Profiler documentation is available here: https://tinkerpop.apache.org/docs/current/reference/#profile-step Can you do traversal.E().has("edgeID", edgeID).profile().next() and paste the output (when

Looking for documentation on how to do profile() - do you have any? Queries like this are also slow: Edge dataSourceToCorrelationEdge = traversal.E().has("edgeID",

Hi folks, From what we are seeing in the gremlin driver code, it is expected that all gremlin server host names are provided and not a VIP. Is that correct? For example, Cluster cluster =

Sorry for the delay. When a request comes in via REST, Quarkus creates a thread to handle it; I believe it actually comes from a thread pool. This code now does:

It's very suspicious. It shouldn't take 3 seconds just to load 3 edges. Can you provide theprofile()​ output here when you see such slowness? It is also worth trying if other queries (e.g. loading a

When you say use JanusGraph.tx().createdThreadedTx() directly, what do you mean? Can you give an example?
