arroy

Overview

Arroy provides efficient on-device vector search with low-latency ANN using LMDB backend.

Features

• Low-latency ANN search with random projection trees
• LMDB for concurrent read/write access
• Configurable n_trees and search_k for latency/accuracy trade-off
• Multi-threaded queries

Use Cases

• IoT real-time similarity search
• On-device AI embeddings management
• CV inference on edge hardware

Comparisons

• On-device low-latency vs cloud Qdrant servers
• Lower memory than Annoy, persistent unlike in-memory only libs
