Andy Seaborne commented on JENA-44:
-----------------------------------
Will JENA-29 (query cancellation) interact with this? (subtext - if not, why
not?!) QueryIterSort has changed.
It does not say explciitly it's originally ASF licensed, just "Copyright
2008-2009 LinkedIn" adjacent to a copy of the BSD license. To be clear, could
the patch please have a mention of the ASL and a trace back to the origin?
This won't be such an issue if we have incorporated the code into ASF SVN but
we haven't.
Thanks - Andy

> In QueryIterSort, the sorting of the contents of an Iterator<Binding> is done
> in memory, using Arrays.sort. This can be problematic where the set to be
> sorted is large. A possible solution could be to use an external, disk-backed
> algorithm. A hybrid approach may be better, whereby we attempt the in-memory
> sort, but when the number of bindings encountered goes over a certain number,
> resort to the disk-backed variant.
