[Zope-Annce] Announcement: DirectoryStorage 1.0 alpha 1

[Toby Dickenson]

Announcing the first alpha release of DirectoryStorage, a ZODB Storage wh=
ich=20
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.
