Hudson commented on JENA-309:
-----------------------------

Integrated in Jena__Development_Test #452 (See [https://builds.apache.org/job/Jena__Development_Test/452/])
    JENA-330 : Streaming support for SPARQL Update queries and streaming support for quads in INSERT DATA / DELETE DATA queries; and 
JENA-309 : If supported by the underlying storage engine, Fuseki can exploit transactions in order to stream SPARQL Update requests (Revision 1440841)

     Result = SUCCESS

>                 URL: https://issues.apache.org/jira/browse/JENA-309
>             Project: Apache Jena
>          Issue Type: Improvement
>          Components: ARQ, Fuseki
>            Reporter: Andy Seaborne
>            Priority: Minor
>
> Fuseki is not aware that some transactions are fully ACID not just locking.
> It could rely on the transaction semantics and not need to buffer request data to verify it.
> Consider a special wrapper to make non-TDB datasets have weak transaction semantics.
> DatasetGraphs need a "capabilities" mechanism.  c.f. c.h.h.j.sparql.util.Context and c.h.h.j.graph.Capabilities.
