It leverages zero-copy data paths, SIMD optimizations, and advanced storage backends to deliver sub-millisecond latency. Key Features - High Performance : Built on Apache Arrow for zero-copy data transfer. - Distributed : Consistent hashing and gossip-based membership (SWIM protocol). - Optimized Storage : Optional io uring WAL backend for high-throughput ingestion. - Hardware Aware : NUMA-aware memory allocation and SIMD vector distance calculations. - Smart Client : Resilient Go SDK that handles request routing transparently. Architecture Longbow uses a shared-nothing architecture where every node is loosely coupled. See Architecture Guide for a deep dive. Getting Started Prerequisites - Go 1.25+ - Linux (recommended for best performance) or macOS Installation Running a Local Cluster Running Benchmarks Longbow includes a comprehensive, multi-platform benchmark suite: GPU Binary Distribution Longbow is compiled natively for CPU architectures by default. To enable GPU acceleration, you must compile or run the specific platform binaries: - macOS (Metal) : Build the universal binary via make build-darwin-universal which utilizes lipo to create a fat binary containing both x86 64 (CPU) and arm64 (Metal) targets. - Linux (CUDA) : Build the CUDA-enabled binary via make build-cuda (requires NVIDIA toolkit).
