In line with #2285, it would be good to support index merge on quantized vectors.
Describe the solution you'd like
The only non-plumbing thing that would need to change in the Fastener implementation is replacing the batched GEMM distance comparisons used to choose leaders and compute intra-partition NNs with quantized distance comparisons. This may be annoying to implement or slow if batched quantized comparisons in the shapes used by these two operations are not already available.
