I've had this issue reported to me in the context of zope.sqlalchemy,
but have been unable to reproduce it. Others have also seen it, but as

I think that moving to an LLTreeSet for the docset will significantly

their parent persistent object's record. Each LOBTree object bucket

I think this means that you are storing all of your data in a single
persistent object, the database root PersistentMapping. You need to
break up your data into persistent objects (instances of objects that
inherit from persistent.Persistent) for the ZODB to have a chance of
performing memory mappi
nality for zope.sqlalchemy - when a large
number of savepoints are used, the eventual commit can lead to a
`RuntimeError: maximum recursion depth exceeded` in SQLAlchemy as it
attempts to unroll its nested substransactions.

It really depends on what you are trying to achieve.
The simplest solution would probably be to use a geohash string within
an OOBTree.
If you need a full geospatial solution, postgis is featureful and easy
to use, and simple to integrate transactionally with ZODB.

Gary,
I have been using the ZODB for about a year and a half with a bookstore
application. I am just now about ready to put it out on the internet for
people to use. I have had the same problem with
Backing up a ZODB has always been fairly easy in the past, but with the
introduction of blobs things have got a little more complex.
How should I create a consistent backup of my Data.fs and blob directory?
My inital guess would be to take a copy of the Data.fs, then take a copy of
the blob dire
Hi Adam,
For incremental backups, I presume the procedure would be to first run
repozo on the Data.fs then run rsync on the blobs directory to the backup
blobs directory.
The concerns would be equivalent to those on doing a full backup.

Broken objects occur when the class for a pickled object cannot be
imported. To change the location of a class, you need to provide an
alias at the old location so that the object can be unpickled, i.e.
MyOldClassName = MyNewClassName. You can only remove MyOldClassName
after you have updated a

There's a fix for this in the Jarn branch. Note that to collect more
interesting data it rolls back the load connection at

For Plone, the standard remedy to this problem is to separate out
portal_catalog into it's own storage (zeo has support for serving
multiple storages). You may then control the object cache size per
storage, setting the one for the portal_catalog storage large enough to
keep all it's objects in

A few weeks ago I converted the "ZODB/ZEO Programming Guide" and a few
more articles into structured text and added them to the zope2docs
buildout. I've now moved them to their own buildout in
svn+ssh://svn.zope.org/repos/main/zodbdocs/trunk and they will soon
appear at http://docs.zope.org/zod
