If DiffType are SAME, MISSING_LHS, or MISSING_RHS they will appear once with no Delta
If DiffType is DIFFERENT, there is one KeyStats for every field that is different for that key
with that field's Delta
key - primary being compared.
diffType - how the two records of the given key compares.
delta - a single field's difference including field name, values, and distance
