Andrzej Bialecki commented on SOLR-10262:
------------------------------------------
Thanks Otis :) Yes, I'm aware of that implementation and the discussion around
it. It's an easy fix to replace the ExponentiallyDecayingReservoir that metrics
use by default with HdrHistogram, there's even a pull request against Codahale
repo with an implementation.
By "making it possible" did you mean that we make it the new default, but we
also allow people to use a different implementation? This would have to be
configured early on in {{solr.xml}} or even via system properties, which is a
bit ugly.

> Since [~ab] is on a role with metrics...
> There is no way to accurately compute request latency percentiles from
