> If the need to retrieve floats from users is not present, is it feasible to skip this rehydration step and directly use the quantized vectors for distance calculations? Quantized vectors are used directly for distance calculations today. We keep the full precision values around for recalculating quantiles during merging. @benwtrent has a nice blog post that explains this – https://www.elastic.co/search-labs/blog/scalar-quantization-in-lucene It could be useful to enable saving disk space at the cost of slower retrieval of float full precision vectors. Some use-cases might have uniform data distributions anyway. -- This is an automated message from the Apache Git Service.
