Duplicate vertex issue with Uniqueness constraints | Janusgraph CQL
Hi Pawan, Your code mirrors the example at https://docs.janusgraph.org/advanced-topics/eventual-consistency/#data-consistency for the greatest part. Are you sure the changes on graphMgmt get committed

Usage of CustomID on Vertexes
Hi Hazal, Your comment is correct: the graph.set-vertex-id feature is not documented further than this, so using it is not advised. You are also right that lookups in the index require additional proc

JanusGraph server clustering with NodeJS
I read some conceptual confusion, so let me try: a single query is handled by a single janusgraph instance (In this case JanusGraph Server) you can handle many queries from many nodejs clients in para

Hi Pawan, 1. See https://docs.janusgraph.org/schema/#displaying-schema-information 2. See the manuals of your storage and indexing backends (and older questions on this list) 3. Please elaborate; some

Queries with negated text predicates fail with lucene
Hi Toom, Yes, you are right, this behavior is not 100% consistent. Also, as noted, the documentation regarding text predicates on properties without index is incomplete. Use cases are sparse, though,

Options for Bulk Read/Bulk Export
Hi, There are three solution directions: if you have keys to your vertices available, either vertex ids or unique values of some vertex property, you can start as many gremlin clients as your backends

Query performance with range
Hi Claudio, Paging with range can only work with a vertex centric index, otherwise the vertex table is scanned for every page. If you just want all results, the alternative is to forget about the rang

Thread goes into Waiting state forever
Hi Tanroop, Does the problem also occur if you replace v() with V().limit(1) inside your query? If not, at what result size does your issue start to occur? Btw, your post has a typo: "user" and "uidx"

Hi Mladen, You are right, your issue is different than the one I mentioned about GraphManager. I mentioned earlier that the JanusGraph test suite covers your use case: https://github.com/JanusGraph/ja

Flatfile for Janusgraph Backend
No, JanusGraph does not have a storage backend for a single-node cluster that persists to single file (such as sqlite would). It is possible though to have a single Cassandra instance co-hosted on you
