ssdb

SSDB supports Redis protocols, allowing existing Redis clients to connect seamlessly, as demonstrated in the PHP example where standard SET/GET commands work without modification.

Built on LevelDB, SSDB ensures data durability across restarts, making it suitable for applications where in-memory data loss is unacceptable, as highlighted in its design philosophy.

Benchmarks show high performance for operations on sorted sets, hashmaps, and lists, with QPS rates over 40,000 for typical operations like hset and zget, indicating efficient disk handling.

Widely deployed by internet companies like QIHU 360, SSDB is battle-tested for large-scale production environments, as noted in the README's emphasis on its reliability.
