> I am a user of Streaming and I am currently trying to use rollups on an 10
> dimensional document.
> I am unable to get correct results on this query as I am bounded by the
> limitation of the export handler which supports only 4 sort fields.
> I do not see why this needs to be the case, as it could very well be 10 or 20.
> My current needs would be satisfied with 10, but one would want to ask why
> can't it be any decent integer n, beyond which we know performance degrades,
> but even then it should be caveat emptor.
