Arroy is an open-source Rust library for efficient similarity search and management of vector embeddings, designed for use in vector database systems. It provides an interface similar to the Annoy Python library and is optimized for memory usage by leveraging LMDB as its backend storage. This allows multiple processes to share and atomically modify the same data.
n_trees: Number of trees used in the index (affects memory and accuracy).search_k: Number of nodes to inspect during a search (affects speed and recall).search_k is not provided, it defaults to n * n_trees where n is the number of neighbors to search for.Arroy is open-source software, free to use under the MIT license.
