Project description

Redis Shelve

Build status
A Python shelve that uses Redis as storage.


In some contexts writing state to files can be hard. Redis can be a more suitable storage solution. If you need a shelve but cannot write to file and if you are friends with Redis already, you can use Redis Shelve.


Redis Shelve is licensed under LGPLv3. See the LICENSE file for details.


pip install redis-shelve


The behaviour of the Redis shelve should be similar to Python shelve. Instead of a filename, you can pass redis-shelve a redis instance. You can think of the configured redis database being similiar to a file in Python shelve.

import redisshelve
from redis import Redis

redis = Redis(db=15)
shelf = redisshelve.RedisShelf(redis=redis)

shelf['test'] = 'Test'
assert 'Test' == shelf['test']
assert 'Test' == shelf.get('test')

You can also use the context manager.

with as shelf:
    shelf['foo'] = 'Bar'

Prefixing keys

By default, the keys you enter in the shelf are used as keys in Redis. If you think this might conflict with existing values, you can prefix your keys.

NB: As a side effect, if you also use writeback, the keys in the shelf's cache are also prefixed.

shelf = redisshelve.RedisShelf(redis=redis, key_prefix='my_prefix')

with, key_prefix='my_prefix') as shelf:
    shelf['foo'] = 'Bar'

More examples.

Please see the tests for more examples.

unprefixed: tests/
prefixed: tests/
