Cachex is an extremely fast in-memory key/value store with support for many useful features:

• Time-based key expirations
• Pre/post execution hooks
• Statistics gathering
• Multi-layered caching/key fallbacks
• Distribution to remote nodes
• Transactions and row locking
• Asynchronous write operations

I just published the first public version (v0.8.0) to Hex, feel free to take a look and try it out!
