Histograms

[ben.t...@booking.com]

I see there is no way to generate histograms directly, am I correct? Is there a plan to do something similar like http://druid.io/docs/latest/development/extensions-core/approximate-histograms.html?

Currently, Pinot has Percentile estimates that uses TDigest library from https://github.com/tdunning/t-digest. I believe it has implementation for histograms as well, and can be easily integrated into Pinot.
