Announcing the first alpha release of DirectoryStorage, a ZODB Storage which uses one file per revision of an object. * A very simple file format. Your data is not locked away inside an unfamiliar, opaque database. * Easy administration. Nearly as easy as FileStorage, and much less touble than BerkeleyStorage. * Use familiar filesystem tools for maintaining the database. For example: * Take an incremental backup using tar. * Make crucial persistent objects immutable using file permissions * Constant memory usage, even during packing. With the right filesystem I believe this makes DirectoryStorage the most scalable Storage available today. Changes since the previous informal release include: * Many bug fixes. DirectoryStorage is now in production use. * A storage checking tool. Detect any problems early. * Additional fault tolerance to reduce the risk of permanent data loss. * Many performance improvements - now within 50% of FileStorage. If you like the idea of a scalable high performance storage with easy administration, but dont yet want to put your data in alpha-quality software, why not join the dirstorage-users mailing list at http://lists.sourceforge.net/lists/listinfo/dirstorage-users
