Exception while creating vertex with custom vertex id
Hi Umesh, No, it is not clear at all whether the issue and cassandra-4.0 are related, but generally it is not useful to report bugs regarding unsupported configurations. To dig deeper, I would be curi

Hi Umesh, On the first line of your first post you state that you use cassandra-4.0. However, support for cassandra-4.0 is still an open issue: https://github.com/JanusGraph/janusgraph/issues/2325 htt

Hi Umesh, Can you please add the graph properties (configs) and the statements for creating the vertex labels in the graph schema (if any)? Cheers, Marc

Hi Matthew, I suppose you mean identifiers instead of indices? The identifier space is per graph. The storage backends make separate files per graph. Marc

Janusgraph embedded multi instance(JVM) data sync issue

Indexing Strategies for RDF edges/predicates on Janusgraph
Hi Matthew, It would be possible to replace the employedBy, isSoldby, isLeasedBy relations with a relatedToCompany relation with employment, selling and lease properties. But I do not see any advantag

Janusgraph embedded multi instance(JVM) data sync issue
Hi Pawan, You are right, if issues already arise without index, you should investigate that first, even though a large graph without indices is useless in itself. See the third question from Boxuan Li

Fastest way to check if a property key is mixed indexed or not
Hi Harshit, The performance impact for JanusGraph when including a property key in multiple mixed indices, is negligable (the selection of the index for a specific query will be a tat slower). Additio

Hmm, these figures seem perfectly reasonable. It seems I was also wrong about the db-cache heap region not being shared between graphs. So you have to gather more information about was is going wrong.
