There was a problem hiding this comment.
Something about this test design seems off. I was expecting to see a test case being added in the spirit of: "Given buckets x, y, & z expect last bucket to be z + 1." Maybe it is too dynamic for its own good? 😄
Anyway doesn't need to be fixed as part of this, just musing.

Haha you're right! It was too dynamic to even catch that issue in the first place 😀
I'll work on fixing this later.

The values for overflow buckets should be serialized as the value-count pair: LastBucketValue + 1,count
For eg. for a Histogram with the boundaries: [25,50,100], if the value recorded is 150, it should be serialized as the following value-count pair: (101, 1)
