Andy Seaborne commented on JENA-267:
------------------------------------
+1 to formally defining some kind of DataBag with a contract of write out,
write back in same order.
SequnceDataBag which simply inherits from DefaultDataBag at the moment.
Then BagFactory.newSequenceDataBag?
This leaves the default choice uncontracted and open for change later.
> SPARQL JSON Parser is not streaming

> Key: JENA-267
> URL: https://issues.apache.org/jira/browse/JENA-267
> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ
> Affects Versions: ARQ 2.9.1
> Reporter: Rob Vesse
> Assignee: Rob Vesse
> Labels: json, sparql
>
> 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
