Q: is it possible to query non-integer percentiles? I'm interested in calculating P99.9, but looking at the supported aggregations doc, it looks like those functions only support up to P99.

Yes, we can support that. Can you please file an issue on GitHub? This feature requires some change on the function name parsing, should be simple. Contributions are very welcome

@Jackie with functions now taking multiple args, do we still need to rely on name parsing?

Good point, we just need to parse double

right now the percentile only takes the integer

Ok, thanks, I filed https://github.com/apache/incubator-pinot/issues/6301. Sadly, I don't have the spare cycles to work on this at the moment, but it's good news that this is an eminently feasible change.

@Amrish Lal in case you want to take up ^^

Yes, I can take a look as soon as my pinot-controller test cleanups are done (close to wrapping that up)
