mongodict 0.1.0

MongoDB-backed Python dict-like interface

So you are storing some key-values in a dict but your data became huge than your memory or you want to persist it on the disk? Then mongodict is for you!

As it uses MongoDB to store the data, you get all cool MongoDB things, like shardings and replicas.

Installation

As simple as:

pip install mongodict

or:

easy_install mongodict

Usage

As it uses collections.MutableMapping as its base, you just need to change the line which creates your dict. For instace, just replace:

>>> my_dict = {}

with:

>>> from mongodict import MongoDict
>>> my_dict = MongoDict(host='localhost', port=27017, database='my_dict',
                        collection='store')

and then use it like a normal dict:

>>> my_dict['python'] = 'rules'
>>> print my_dict['python']
'rules'
>>> del my_dict['python']
>>> print my_dict['python']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "mongodict.py", line 23, in __getitem__
    raise KeyError
KeyError

Enjoy! :-)

Note

There is no kind of in-memory cache, so all key lookups will be translated in a MongoDB query but as MongoDB’s server put everything it can in memory, probably it’ll not be a problem (if your working set is always entire in memory).
