bigdict
bigdict implements a persisted, out-of-memory dict for Python.
The usage API strives to be as close as possible to the built-in dict, with a small number of extras.
The "engine", or "back-end", is currently lmdb. However, lmdb is not the point; the point is rather a "persisted, out-of-memory dict". Criteria used in choosing the engine:
- It must be embedded, as opposed to client/server.
- It must be a mature project with a reliable Python binding.
In addition,
- It must use more files for storage as the data size grows, hence keeping file sizes modest, as opposed to a single file growing in size.
If the chosen backend does not meet this requirement, it's the responsibility of bigdict to implement that.
Installation:
$ pip install bigdict
