David Smiley commented on SOLR-6216:
------------------------------------

[~tomasflobbe] , do you have any scripts for your performance testing?  I am 
impressed with that part specifically as I've got some interval faceting on my 
horizon to do what is somewhat similar to what you've got here LUCENE-5735

> Better faceting for multiple intervals on DV fields

> There are two ways to have faceting on values ranges in Solr right now: 
> “Range Faceting” and “Query Faceting” (doing range queries). They both end up 
> doing something similar:
> {code:java}
> searcher.numDocs(rangeQ , docs)
> {code}
> The good thing about this implementation is that it can benefit from caching. 
> The bad thing is that it may be slow with cold caches, and that there will be 
> a query for each of the ranges.
> A different implementation would be one that works similar to regular field 
> faceting, using doc values and validating ranges for each value of the 
> matching documents. This implementation would sometimes be faster than Range 
> Faceting / Query Faceting, specially on cases where caches are not very 
> effective, like on a high update rate, or where ranges change frequently.
> Functionally, the result should be exactly the same as the one obtained by 
> doing a facet query for every interval
