Overview
A Distribution may optionally contain a histogram of the values in the population. The histogram is given in +bucket_counts+ as counts of values that fall into one of a sequence of non-overlapping buckets. The sequence of buckets is described by +bucket_options+.
A bucket specifies an inclusive lower bound and exclusive upper bound for the values that are counted for that bucket. The upper bound of a bucket is strictly greater than the lower bound.
The sequence of N buckets for a Distribution consists of an underflow bucket (number 0), zero or more finite buckets (number 1 through N - 2) and an overflow bucket (number N - 1). The buckets are contiguous: the lower bound of bucket i (i > 0) is the same as the upper bound of bucket i - 1. The buckets span the whole range of finite values: lower bound of the underflow bucket is -infinity and the upper bound of the overflow bucket is +infinity. The finite buckets are so-called because both bounds are finite.
+BucketOptions+ describes bucket boundaries in one of three ways. Two describe the boundaries by giving parameters for a formula to generate boundaries and one gives the bucket boundaries explicitly.
If +bucket_boundaries+ is not given, then no +bucket_counts+ may be given.
