(short: int64), and each element represents the bucket population as a delta to
the previous bucket in the list. The first bucket in each list contains an
absolute population (which can also be seen as a delta relative to zero). The
deltas MUST NOT evalute to a negative absolute bucket population.
deltas MUST NOT evaluate to a negative absolute bucket population.

To map buckets in the lists to the indices as defined in the previous section,
there are two lists of so-called _spans_, one for the positive buckets and one

case of a native histogram, the cost for the single histogram might already be
lower if the classic histogram featured a high resolution. After partitioning,
the total number of populated buckets in the labeled native histograms will be
signifcantly smaller than 100 times the number of buckets in the original
significantly smaller than 100 times the number of buckets in the original

layouts](#compatibility-between-histograms), their mergeability is still
fundamentally limited. The reconciliation only retains exact matches of bucket
boundaries between the involved NHCBs. This yields useful results, if most
bucket boundaries match. However, abitrary changes in the bucket layout can
bucket boundaries match. However, arbitrary changes in the bucket layout can
easily create a situation where none of the boundaries match, resulting in a
histogram with only one bucket (the overflow bucket).
