Hi Ganesh,
Are the results a SPARQL Result Set or a RDF Graph?
For a SPARQL result Set, formats such as aplication/sparql-results+json
do actually stream so you can process the results without having t have
them all in the client at the same time.
For an RDF Graph, you can load a persistent TDB store.
There isn't any code in Jena to put graphs or results sets on a Kafka
queue but given the steraming nature of the returns, you could write
code to do that without needing everything in RAM at any point.

Hello All,
I just started working on Jena and had a question I was hoping one of you could
help me with. I have a Hugh pdf store and the after I make my query, I will
have to convert the result to JSON format and store it elsewhere. The problem
is, the returned result is too huge to store in the ram. Thus I wanted to know
if I could directly put the returned answer to a Kafka queue, or read the
returned result in parts. Is this possible? Please let me know.
Thanks,
Ganesh
