If we were to a dd a config option what would it look like? I guess the key elements are: quantization is one-and-done; no re-evaluation on merging, and therefore any data required only for indexing can be dropped. This could be true whether or not some higher-precision vectors are preserved for re-ranking. I mean it's conceivable we'd want to quantize at 1 bit for recall and 8 bits for re-ranking? To me the key choice is whether to re-evaluate quantization bounds on merge. I actually wonder if with OSQ this is ever necessary since it is computing bounds per-vector? -- This is an automated message from the Apache Git Service.
