Allow k and M suffixes in IVF indexes #3812

Closed mdouze closed 2 months ago

mdouze commented 2 months ago

Summary: Allows factory strings like IVF3k,Flat as a shorthand for 3072 centroids.

The main question is whether k or M should be metric (k=1000) or power of 2 (k=1024):

The suffixes ki and Mi should be used for powers of 2 but this makes the notation more heavy (which is what we wanted to avoid in the first place).

So I picked power of 2.
