The `dense_vector` type supports quantization to reduce the memory footprint required when <<approximate-knn, searching>> `float` vectors.
The two following quantization strategies are supported:

+
--
`int8` - Quantizes each dimension of the vector to 1-byte integers. This can reduce the memory footprint by 75% at the cost of some accuracy.
`int4` - Quantizes each dimension of the vector to half-byte integers. This can reduce the memory footprint by 87% at the cost of some accuracy.

To use a quantized index, you can set your index type to `int8_hnsw` or `int4_hnsw`. When indexing `float` vectors, the current default
