I have lots of data that I currently store in dictionaries. However,
the memory requirements are becoming a problem. I am considering
using a database of some sorts instead, but I have never used them
before. Would a database be more memory efficient than a dictionary?
I also need platform independence without having to install a database
and Python interface on all the platforms I'll be using. Is there
something built-in to Python that will allow me to do this?
Since you use dictionaries, I guess that simple store saving key:value
will do?
If so, bsddb support built into Python will do just nicely.
bsddb is multiplatform, although I have not personally tested if a
binary db created on one platform will be usable on another. You'd have
to check this.
Caveat: from what some people say I gather that binary format between
bsddb versions tends to change.
There's also ultra-cool-and-modern Tokyo Cabinet key:value store with
Python bindings:
http://pypi.python.org/pypi/pytc/
I didn't test it, though.
