It optimizes for storage space: Even though there are ANN libraries producing reasonable recall in less than 1 ms, for our use case we can accept sacrificing some of that speed for reduced server costs.

It seems that it only fits in their own business scenario, not in a general approximate nearest neighbor search.

@chasingegg curious if you can elaborate. what's different with the scenario they are trying to optimize for?
