GitHub - dadgar/onecache: OneCache is a best-effort, replicated KV store accessible via the memcached protocol
OneCache is a distributed key/value store that is accessible via the memcached protocol. OneCache nodes natively support clustering and best effort replication. Adding nodes into the cluster effectively increases the in-memory storage capability of the cache. Replication of keys minimizes the impact of a single node failure as requests will transparently be forwarded to the new key leader. OneCach
