Re: Driver's for java connectivity

Vinayak, If your goal is simply to get your entire graph into a JSON-based format, you may want to consider GraphSON (http://tinkerpop.apache.org/docs/3.4.1/dev/io/#graphson). Kevin

Re: Driver's for java connectivity

Hi Kevin, To verify whether the issue is from the server or client-side, we are trying to execute the same query on the server and output the data in the file. But still it's not possible. Janusgraph

Re: Driver's for java connectivity

Vinayak, Is the out of memory error in the server or the client? And are Janusgraph and Cassandra running in the same JVM or are you running Cassandra separately? And what is your use case for your

Re: Driver's for java connectivity

Hi Kevin, JVM size at the server where janusgraph and Cassandra (same machine) is set to 24GB. On the API side, we tried setting it to 8GB. Is there any other way using which we can write the query

Re: Driver's for java connectivity

Vinayak, What about the memory settings, specifically the max heap, for the JVM Janusgraph is running in? Your traversal is effectively retrieving your entire graph. Is that really what you need to

Hi Kevin, Query: g.V().as('a').outE().as('b').inV().as('c').select('a','b','c').by(valueMap().by(unfold())) Memory Settings: maxInitialLineLength: 4096 maxHeaderSize: 8192 maxChunkSize:

Re: Driver's for java connectivity

Vinayak, What is the query? It sounds like whatever it is requires instantiating a lot of objects in order to process the results and construct the JSON. What are your memory settings for the

Re: Driver's for java connectivity

Hi Marc, While trying to execute a query using HTTP throws an out memory error. The number of records returned is more hence can't get the entire output. I want an entire output of the query in the

Hi All, There is a requirement to enable the JMX authentication of Cassandra. The steps followed are as follows: 1. cd /home/user1/janusgraph-full-0.5.2/conf/cassandra 2. vi cassandra-env.sh 3.

Re: How to circumvent transaction cache?

Hi Timon, what exactly is your data storage setup? For example, if you are using Cassandra (with replication) then there is no guarantee your current transaction can read latest value right after

Re: Driver's for java connectivity

Hi Vinayak, What actually is the "desired operation", it is not clear to me? In other words, what is the result after you have run the desired operation? Best wishes, Marc

Re: Script16.groovy: 2: unable to resolve class StandardJanusGraph

Hi Vinayak, What may confuse you is that the gremlin console does a lot of under the hood imports, but it doesn't import all janusgraph classes. So, you can solve this in two ways: Preferred: rather

Re: Authentication in JanusGraph Server

Thanks for looking at it Marc, and for raising the issue. As you say, we can work around the issue by using a different persistent store, but I must admit to being intrigued as to why it seems to not

Hi All, Using a batch processing script to load the data into the graph. With JanusGraphFactory the scripts were working as expected. Now the same code is not working with ConfiguredGraphFactory. The

Re: Question on Design and Suitability of janus graph

Hi Basanth Gowda, The fit between your use case and janusgraph does not seem particularly good. The mean reasons for my opinion are: your datamodel still seems rather simple (website visitors and
