Description
BBQ or Better BInary Quantization is based on RaBitQ and it's the current algorithm supported in Lucene and Elasticsearch. We are being asked by multiple Lucene users to accept a "dataset" of vectors in the CAGRA build() API. The challenge is that the BBQ algorithm requires some additional state to be carried along for correction codes, which need to be considered during search. This means the dataset needs to be specialized for a BBQ quantizer.
