Description
num_finite_buckets
int
The number of finite buckets. With the underflow and
overflow buckets, the total number of buckets is
num_finite_buckets + 2. See comments on
bucket_options for details.
growth_factor
float
The i'th exponential bucket covers the interval [scale \*
growth_factor^(i-1), scale \* growth_factor^i) where i
ranges from 1 to num_finite_buckets inclusive. Must be
larger than 1.0.
scale
float
The i'th exponential bucket covers the interval [scale \*
growth_factor^(i-1), scale \* growth_factor^i) where i
ranges from 1 to num_finite_buckets inclusive. Must be > 0.
