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 Janusgraph server?

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 file JSON format. Size of graph nodes: 7 lakh and edges: 3 lakh.

Thanks & Regards,

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
