minikeyvalue

minikeyvalue is a compact distributed key-value store designed to avoid the complexity of larger distributed filesystems. The codebase is roughly 1,000 lines while supporting replication, multiple machines, and multiple drives per machine. It is optimized for comparatively large values between about 1 MB and 1 GB and is intended to scale to very large collections. Standard nginx instances act as volume servers, while filesystem storage holds blobs and LevelDB maintains the index. A simple HTTP API handles reads, writes, deletes, virtual deletes, and key listing, with partial S3 compatibility. The system can rebuild its index and rebalance data when storage volumes are added or removed.
