Ray Tracing BVH equivalent for AI vector embedding search?

For a while now I've wanted a generalized higher dimensional acceleration structure for AI vector embeddings that is conceptually similar to ray tracing bounding volume heirarchies.

What do y'all think. For millions of high dimensional vectors, what new precomputable and incrementally updatable data structures do you think will be useful?

Personally, I'm looking for an efficient nearest neighbour and other efficient 'intersection' tools (e.g. finding a vector most similar to a group of n vector embeddings or finding m pre computed groups that are similar by some distance calculation to a specific embedding).
