FW: Edge Index Creation Error
What JanusGraph version do you use? Recent TinkerPop versions use Order.asc instead of Order.incr. Best wishes, Marc

Removed graphs still open in muti node cluster
Hi Lixu, JanusGraph-0.6.0 had various changes to the ConfiguredGraphFactory which might have solved your issue: https://github.com/JanusGraph/janusgraph/issues/2236 https://github.com/JanusGraph/janus

Importing a schema
Hi Laura, JanusGraph only allows to configure a custom SchemaMaker with the schema.default property. Googling on SchemaMaker hits some (unmaintained?) projects that could help: https://github.com/grap

JanusGraph database cache on distributed setup
How fast is immediately? A well dimensioned cassandra or scylladb cluster (with its own block cache!) should be able to serve requests at the ms level. https://www.scylladb.com/2017/09/18/scylla-2-0-w

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, 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
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

Hi Pawan, OK, let's investigate further. You say that the issue occurs for both vertex creation and modification. Let's take the clearest case first: vertex creation with an indexed property. So, in y
