I just released the first version (0.1) of BlitzDB, an embeddable, document-based database written entirely in Python. The software is open-source and released under the MIT license, the code is available on Github:
The documentation is hosted on ReadTheDocs:
The database ships with a native, file-based backend that has no external dependencies. In addition, it can be used as a wrapper around third-party database engines such as MongoDB. Some more features:
* document-based, object-oriented interface * powerful and rich querying language comparable to MongoDB * deep document indexes on arbitrary fields * compressed storage of documents * support for multiple backends (e.g. file-based storage, MongoDB) * support for database transactions (currently only for the file-based backend)
The current, fully functional release is on PyPi (https://pypi.python.org/pypi/blitzdb/0.1) and can be installed using e.g. pip or easy_install:
pip install blitzdb #or easy_install blitzdb
The main motivation for writing this was to create an embeddable, document-oriented database that I could use in my Python projects (e.g. command line tools) without having to worry about setting up and maintaining additional software or servers. The project is NOT intended as a fully-fledged replacement for MongoDB or other document databases.
I would love to hear your feedback on this project and I'm actively looking for contributors, so feel free to get in touch with me (you can find my e-mail on Github).
Best regards Andreas
