kasper-cache

One cache interface, swappable backends. Switch from in-memory to Redis by changing a URL, not your code.

pip install kasper-cache          # in-memory
pip install "kasper-cache[redis]" # + Redis backend

from kasper_cache import Cache

cache = Cache.from_url("memory://")        # or "redis://localhost:6379/0"

cache.set("user:1", {"name": "Mallik"}, ttl=60)
cache.get("user:1")                        # -> {"name": "Mallik"}
cache.get_or_set("user:1", lambda: load(1), ttl=60)

@cache.memoize(ttl=30)
def expensive(x):
    ...

Why

• One interface (get/set/delete/get_or_set/memoize) over many backends.
• get_or_set guards against the thundering-herd on a cache miss.
• In-memory is per-process and fast; Redis is shared and survives restarts.
