Hi Vinayak, Yes, it should be possible to improve on the 3% CPU usage. The newTransaction() should be added to line 39 (GraphTraversalSource g = graph.traversal();) as the global g from line 121 is

Re: Data Loading Script Optimization

Hi Marc, The storage backend used is Cassandra. Yes, storage backend janusgraph and load scripts are on the same server. specified storage.batch-loading=true CPU usage is very low not more than 3

Re: Data Loading Script Optimization

Hi Vinayak, What storage backend do you use? Do I understand right that the storage backend and the load script all run on the same server? If, so, are all available CPU resources actively used during

Re: Not able to enable Write-ahead logs using tx.log-tx for existing JanusGraph setup

No. It should work well for your existing JanusGraph setup too. Note that it is a GLOBAL option so it must be changed for the entire cluster. See

Not able to enable Write-ahead logs using tx.log-tx for existing JanusGraph setup

Hi All, I am trying to enable write-ahead logs by using the config property: tx.log-tx to handle transaction recovery. It's working fine for new JanusGraph setup but not working for Janusgraph setup

Re: config skip-schema-check=true is not honored for HBase

Hi Jigar, Yes, I think it is an issue. I did not fully dive into it, in particular I did not check whether any tests exist for the "disable schema check" configuration option. So, go ahead and create

Data Loading Script Optimization

Hi All, I have attached a groovy script that I use to load data into janusgraph. The script takes 4 mins to load 1.5 million nodes and 13 mins to load approx 3 million edges. The server on which

Re: Property keys unique per label

Hi Laura, Thanks for explaining in more detail. Another example is a "color" property. Different data sources could use different types of color objects. As long as you do not want to query for paints

Re: Property keys unique per label

Janus describes itself like this a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine

Re: Property keys unique per label

Hi Laura, Indeed, unique property key names are a limitation. But to be honest: if two properties have a different data-value type I would say these are different properties, so why give them the same

Property keys unique per label

The documentation says "Property key names must be unique in the graph". Does it mean that it's not possible to have property keys that are unique *per label*? In other words, can I have two distinct

Re: janusgraph and deeplearning

Hi Jonathan, One thing is not yet clear to me: does your graph fit into a single node (regarding memory and GPU) or do you plan to use distributed pytorch? Either way, I guess it would be most

Re: How to split graph in multiple graphml files and load them separately

Hi Laura, Without checking this in the code, it only seems logical that the graph id is ignored, because you have to supply the io readers with an existing Graph instance. Apparently it was chosen to

Re: Performance Improvement

Laura that is helpful, will go through it and try to implement it. Also, if there are any configurations that can be tuned for better performance, please share them.
