rc, the redis cache

Project Description

rc - the redis cache.

  • easy to use
  • can build cache cluster
  • batch-fetch multiple cache results (do it in parallel for cluster)

For full documentation see rc.readthedocs.org.

Installation

$ pip install rc

Quickstart

A minimal cache example looks like this:

from rc import Cache

cache = Cache()
assert cache.set('key', 'value')
assert cache.get('key') == 'value'
assert cache.get('foo') is None
assert cache.set('list', [1])
assert cache.get('list') == [1]

A cache cluster use a redis cluster as backend:

from rc import CacheCluster

cache = CacheCluster({
    'cache01': {'host': 'redis-host01'},
    'cache02': {'host': 'redis-host02'},
    'cache03': {'host': 'redis-host03'},
    'cache04': {'host': 'redis-host04', 'db': 1},
})

Cache decorator:

@cache.cache()
def load(name, offset):
    return load_from_database(name, offset)

rv = load('name', offset=10)

Batch fetch multiple cache results:

assert cache.get_many('key', 'foo') == ['value', None]

# for cache decorated function
@cache.cache()
def cached_func(param):
    return param

results = []
# with the context manager, the function
# is executed and return a promise
with cache.batch_mode():
    for i in range(10):
        results.append(cached_func(i))
for i, rv in enumerate(results):
    assert rv.value == i

Cache invalidation:

cache.delete('key')
# for decorated function
cache.invalidate(load, 'name', offset=10)
