Hi All, I have created a transaction log in hbase as backend using following code. JanusGraphTransaction tx = graph.buildTransaction().logIdentifier("addedPerson").start(); JanusGraphVertex u = tx.add

Hi All, The objective is to count the number of nodes and edges. Query: g2.inject(1).union(V().has('title', 'A').aggregate('v1').union(outE().has('title', 'E1').aggregate('e').inV().has('title', 'B'),

Which, if any, of the graph configuration properties are dynamic? In particular, I would like to toggle `storage.batch-loading`.

Hi All, To avoid a situation of duplicate vertex creation due to parallel transactions, we are using index uniqueness over property which defines uniqueness of vertex. As per doc, we need to specify l

Hello, while debugging some Apache Spark jobs that process data from a Janusgraph graph. i noticed some issues with self-loop edges (edges that connect a vertex to itself). The data is read using: jav

Hi all, We've been integrating our pipelines with Janusgraph for sometime now, it's been working great, thanks to the developers! We use the transaction recovery job and enabled batch-loading for perf

Hi Community/Team, I see that Janus graph can be integrated with multiple storage backends like Cassandra and BigTable. I am trying to evaluating which storage backend is more performant for Janus Gra
