BDBDatastore 0.1 released
When I announced BDBDatastore just a few days ago, it was still a ways away from being practically usable for anyone wanting to develop or deploy App Engine apps. The purpose of the post was twofold: To attract some initial interest, and to motivate me, with the light of public scrutiny, to make sure it gets finished and polished.
I'm pleased to say that release 0.1 is now available. Version 0.1 brings BDBDatastore to parity with the feature set the App Engine datastore had on release day - that is to say, fully featured except for __key__ queries. Along with the server itself, I've also provided a patch to the App Engine SDK that allows you to tell the Python dev_appserver to use BDBDatastore for backend storage.
Full installation and usage instructions can be found on the wiki. Note that this release is still very much beta. It shouldn't break, but it might (and if it does, please let me know). It's also possible (likely, even) that the datastore will change in backwards-incompatible ways between now and 1.0.
As always, feedback and comments are appreciated.
