pylibmc is a Python wrapper around TangentOrg's libmemcached library.
The interface is intentionally made as close to python-memcached as possible,
so that applications can drop-in replace it.
Example usage
=============
Create a connection and configure it::
>>> import pylibmc
>>> m = pylibmc.Client(["10.0.0.1"], binary=True)
>>> m.behaviors = {"tcp_nodelay": True, "ketama": True}
Nevermind this doctest shim::
>>> from pylibmc.test import make_test_client
>>> mc = make_test_client(behaviors=m.behaviors)
Basic operation::
>>> mc.set("some_key", "Some value")
True
>>> value = mc.get("some_key")
>>> value
'Some value'
>>> mc.set("another_key", 3)
True
>>> mc.delete("another_key")
True
>>> mc.set("key", b"1") # bytes or int is fine for incrementing, str is not
True
Atomic increments and decrements::
>>> print(mc.incr("key"))
2
>>> print(mc.decr("key"))
1
Batch operation::
>>> mc.get_multi(["key", "another_key"]) == {'key': b'1'}
True
>>> mc.set_multi({"cats": ["on acid", "furry"], "dogs": True})
[]
>>> mc.get_multi(["cats", "dogs"]) == {'cats': ['on acid', 'furry'], 'dogs': True}
True
>>> mc.delete_multi(["cats", "dogs", "nonextant"])
False
>>> mc.add_multi({"cats": ["on acid", "furry"], "dogs": True})
[]
>>> mc.get_multi(["cats", "dogs"]) == {'cats': ['on acid', 'furry'], 'dogs': True}
True
>>> keys_set = mc.add_multi({"cats": "not set", "dogs": "definitely not set", "bacon": "yummy"})
>>> set(keys_set) == set(['cats', 'dogs'])
True
>>> mc.get_multi(["cats", "dogs", "bacon"]) == {'cats': ['on acid', 'furry'], 'bacon': 'yummy', 'dogs': True}
True
>>> mc.delete_multi(["cats", "dogs", "bacon"])
True
