pub const TAG_HINTS: usize = 16;Expand description
How many leaves the per-keyspace append hint remembers at once.
Bounded and constant (Law 1): the cache never grows with the store, and a slot it cannot spare costs one ordinary descent, never an answer. Sixteen is chosen from the shape of the write, not from taste: the multimodel load writes at most a handful of tags per document (mapping, row, vector, forward edge, reverse edge, field index) and the reverse-edge tag alone needs two – a near-ascending run over people and a second, far lower run over the hundred organizations – so the working set is single digits with room left for the indexes a collection adds.
