Using Approximate k-Nearest Neighbourhood Queries (Support for Integrating Popular ANN Libraries and Using as a Proximity Backend)

Created by: kayuksel

Would it be possible to integrate and use any of the approximate k-NN libraries such as HNSWLIB, FAISS (Facebook), ANNOY (Spotify), or SCANN (Google) with many proximity-based methods, which are implemented in this library?

Do you plan to provide support for their integration? I strongly believe that several people like myself could prefer to have approximate results much faster, especially for large datasets; and this could be a great addition to this library.
