Subject Re: Stats vs Analytics

Just to add more discussion to the mix, we're also building/using this at
    "Percentiles for facets, pivot facets, and distributed pivot facets"

It is an extension to (distributed pivot) faceting that allows stats to be
collected within the faceting component. We built it with the following
1) Supports pivot faceting (stats at each level)
2) Supports distributed statistical operations

If you look at slide 41 of this presentation, you'll get a really good feel
for what this patch does:

The primary focus initially was on calculating percentiles of numerical
values in a distributed way (using bucketing similar to range faceting),
but we are also in the process of adding distributed sum. Other
distributable calculations are possible, we just haven't needed them yet so
we haven't added them.
