Percentiles
Compute estimated percentile values using counts for well known buckets. See spectator PercentileBuckets for more information. The input will be grouped by the percentile key with each key value being the bucket index. The output will be one line per requested percentile.
Value parameters
- expr
-
Input data expression. The value should be a sum or group by. The group by list should include the 'percentile' key. If using the
:percentilesword to construct the instance then other aggregate types, such as max, will automatically be converted to sum and thepercentilekey will be added into the group by clause. - percentiles
-
List of percentiles to compute. Each value should be in the range [0.0, 100.0].

Concrete methods
The underlying data expressions that supply input for the evaluation. These are used to fetch data from the data stores. There may be some expressions types that generate data and will have an empty set. Examples are constants, random, or time.

Returns the final grouping for the expression. For non-grouped expressions this will be an empty list. If a multi-level group by is used, then this will return the grouping of the final result and ignore any intermediate groupings.
