About alibaba/ApsaraCache
ApsaraCache is an archived open-source Redis branch originating from Alibaba Group, based on Redis official release 4.0. It extends Redis with support for both Memcached protocols (classic ASCII and binary), enabling direct use as a Memcached replacement without client modifications, while also providing data persistence. ApsaraCache delivers a 30% performance improvement in short connection scenarios compared to vanilla Redis and has been proven stable and efficient in production environments. The project is licensed under BSD-3-Clause and is now read-only.
