>             Project: Apache Jena
>          Issue Type: Improvement
>          Components: ARQ
>    Affects Versions: ARQ 2.9.1
>            Reporter: Rob Vesse

> The current SPARQL JSON parser in ARQ parses the JSON by parsing the entire response into a in-memory data structure and then iterating over that.  So for large results it is trivial to hit an OutOfMemory exception.
> This task is to reimplement the SPARQL JSON parser to be fully streaming in its implementation in line with all the other results parsers
