Failing to update existing vertices in a batch (TraversalInterruptedException)
Hello,
I'm updating some properties of vertices in janusgraph in batches.
One batch may contain up to 5000 vertices updates.
Underline db is hbase.
While doing those updates i receive the following

Re: keys are not indexed
This is equivalent to disable force-index.
Is there any way i can use index power to speed up this operation.
Also when i execute this i am getting below exception:

Re: PageRank on Large Graph
Hi Marc,
Ah - I see the output in /user/username/output/~g. This appears to be gryo format. Thank you! Do you know of a way to update the actual JanuGraph with a new page rank

Re: Janusgraph Temporary backend operation
Hi Misha,
You are right.
We are at the requirement of inserting and updating vertices to janusgraph where we need an insert frequency of 500,000 vertices per second and update frequency of 5000

Re: janusgraph/gremlin server log : waiting for 1 actions to finish on table: janusgraph
As the messages state, HBase client is using async processing, so the operations are processed in the background. This is saying how many actions are left to process, and what regions they are going

Hi Dilan,
Looks like you're using the HBase backend, and this is an INFO level exception telling you that when issuing many mutations in parallel ("mutateMany"), some of the mutations succeeded, while

Re: keys are not indexed
You can do OLAP without indexes which will do full scans: g.withComputer().V().has('mobile')

Re: Multiple writers cause inconsistent vertices
The way we handled it was to not use locks or a unique index, but do keep a non-unique index, but then accept that there may be duplicate vertices and either construct our traversals to handle it, or

Re: Multiple writers cause inconsistent vertices
Hi Ajay,
If at all possible, I usually try to remove the need for unique constraints on indexes. You mentioned that eventually
you'll have about a 99:1 r/w ratio. Does this mean that you'll do a big

Re: Searching with composite indexes - performance gradually decreases
No, and for your use-case, a mixed index will result in worse performance.

Hi Dilan,
What backing store are you using? Also are you running Janus embedded or does your client hit gremlin server remotely? I'll assume you're using Cassandra just to give you a few things to

Re: PageRank on Large Graph
Hi Joe,
Regarding not finding the OLAP output, did you try this section of the TinkerPop ref docs?

Re: Mixed index is not used by Gremlin query
Hi Dale,
the index was originally defined before data ingestion. Actually, some vertices (for schema description) were already existing.
After ingesting the nodes (real repository ones), ElasticSearch
