the prefix is stored as the second part
of the column name it's easy to map back to the original word.
Your data blow up will be of the order of the average word length.
Increased storage and write load is a standard trade-off when
denormalising to gain some advantage/flexibility at query time.

Overlapping refers to the range of keys. The key ranges contained within the

s node. If one appears in the history and the other does
not, it is probably safe to assume that the old NodeId was not deleted from
the CurrentLocal row correctly, and so you could try removing it from there
manually.
