----
> allow ORDER BY sort to be cancelled
> -----------------------------------
>
> Key: JENA-1212
> URL: https://issues.apache.org/jira/browse/JENA-1212
> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ
> Reporter: christopher james dollin
> Priority: Minor
> Fix For: Jena 3.1.1
>
>
> When a query with an ORDER BY is cancelled, the component
> Arrays.sort() that sorts the chunk(s) of the result
> bindings runs to completion before the cancel finishes.
> [See QueryIterSort and SortedDataBag.]
> For a large result set, this results in a long wait
> before the cancelled request finally finishes. This
> can be inconvenient.
