About

Pycortex is a very simple caching server. It can store string key/value pairs. Both the server and the client library are built using asyncio.

Protocol details

• Requests and responses are sent as JSON.
• Keys must be alphanumeric
• Values are utf-8.

Requests to server

• Set: {"m": "SET", "k": , "v": }
• Get: {"m": "GET", "k": }
• Evict: {"m": "EVICT", "k": }
• Clear: {"m": "CLEAR"}

Responses from server

• Cache hit (Get): {"v": , "e": False}
• Error (Get, Evict): {"v": None, "e": True}
• Ack (Set, Evict, Clear): {"v": None, "e": False}

Configuration

• It is possible to set the maximum number of entries in the cache by setting the environment variable PYCORTEX_ENTRY_LIMIT to the desired limit.
