Dobbin

Dobbin is a transactional object database for Python 2.6 or higher. It's a fast and convenient way to persist Python objects on disk.

Features:

• MVCC concurrency model
• Implemented all in Python
• Multi-thread, multi-process with no configuration
• Zero object access overhead in general case
• Optimal memory sharing between threads
• #fficient storing and serving of binary streams
• Architecture open to alternative storages

What is new in this release:

• Add support for Python 3.
• Use C-optimized pickle module when available.

What is new in version 0.2:

• Subclasses may now override existing methods (e.g. __setattr__) and use super to get at the overriden method.
• Transactions now see data in isolation.
• When a persistent object is first created, its state is immediately local. This allows an __init__ method to initialize the object.
• Added method to create a snapshot in time of an existing database.
• Added PersistentDict class.
• The Persistent class is now persisted as changesets rather than complete object state.
• Set up tests to run using the nose testrunner (or using setuptools).

Requirements:

• Python
