Hi Srinivas, Do I understand right that you get this error on restarting of gremlin server? How does the yaml config file for gremlin server look like? Best wishes, Marc

Re: Script16.groovy: 2: unable to resolve class StandardJanusGraph

Hi Vinayak, If I understand it right (did not test it), you have to use two gremlin consoles: Use one gremlin console to connect to your server and use ConfiguredGraphFactory. This will manage which

Re: How to circumvent transaction cache?

My thoughts are: 1) As you said, you wanted to be able to disable the transaction cache so that you can read from database again. I have provided a solution here:

Re: Multiple vertices generated for the same index value and vertex properties missing with RF3

Hi Saurabh, To be sure, in the valueMap(true) return value I see both the id token and an "id" property key appear (I am not even sure whether an "id" property key is allowed). Is this "id" property

Hi Marc, The same code works for JanusGraphFactory but not for ConfiguredGraphFactory. I investigated issue further. For ConfiguredGraphFactory we establish remote connection using following

Hi all We are using janusgraph at zeotap at humongous scale (~70B V and 50B E) backed by scylla. Right now I am facing an issue in janusgraph_ids table, wherein there are large partitions created in
