Hoss Man commented on SOLR-3583:
--------------------------------

FWIW: I haven't spent a lot of time looking at this patch, but from what i've 
seen of the syntax for requesting percentiles, it seemed kind of cumbersome to 
me.

I've opened a couple of issues (SOLR-6350 & SOLR-6351) which i think could give 
us all the functionality described here -- plus a lot more flexibility through 
a more general mechanism of computing stats per pivot.

I also think that in general, leveraging the "tdigest" library to do 
distributed percentiles seems like better idea then reinventing the wheel 
ourselves.
