Re: Template configuration parameters with comma-separated lists in Janusgraph 0.6.0
Hi Mladen,
I can confirm this is indeed a bug. I apologize that when writing the test, I didn't notice the second open call was just returning the cached instance. Thank you for reporting and fixing

Re: Flatfile for Janusgraph Backend
Hi,
JanusGraph supports Oracle Berkeley DB which is embedded into Java and works either with a filesystem (by default) or in-memory (if configured so).
That's might be something what you are looking

Hi Oleksandr,
Thank you for the detailed explanation, regarding the configuration and indexes. I will dig deeper into it and try to resolve the problem.

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

Potential transaction issue (JG 0.6.0)
The issue can be reproduced within certain conditions, I cannot find a recipe to reproduce it on any environment
We have a query of type
g.inject((int) 1).union(...).limit(5L)

Re: 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

Flatfile for Janusgraph Backend
Hi Team,
I am working on the issue and want to i am using HBase and Solr for our current setup of Janusgraph.
Is that possible to replace HBase with a flat-file, instead of an in-memory backend?

Re: Can we find connected nodes without using gremlin query
Hi Anjani,
In individual query for a subgraph of 40 nodes will typically take between 0.1 and 1 seconds (with scyllaDb being the fastest storage backend). The number of 200 TPS can be reached easily

Re: Can we find connected nodes without using gremlin query
Thanks Marc for response.
Our graph is very large around 1TB, so can not hold in memory.
Subgraphs that we want to retrieve can have 30 -40 connected nodes.
We have requirement of around 200 TPS.
