Probably not. If you had an SQL solution, and some client code said someArticle.NumberOfReaders += 1, how would you get that assignment to fire off your SQL code?

You might consider replacing the NumberOfReaders attribute with a first-class persistent object. e.g. you could use a PersistentList or IIBTree or some such. This would prevent Zope from saving the entire Article object when that one attribute changes. You'd still get some bloat from all the historical revisions of the attribute, but it would be MUCH less. e.g. something like: from ZODB import PersistentList class Article(...): def __init__(self): ... self._numberOfReaders = PersistentList([0]) def getNumberOfReaders(self): return self._numberOfReaders[0] def incrementNumberOfReaders(self): # do NOT set self._p_changed = 1 self._numberOfReaders[0] = += 1 You could then have NumberOfProperties become a ComputedAttribute to allow client code to keep accessing it as an attribute. (this is a read-only "property" in recent versions of Python, not to be confused with Zope's "properties"; but Zope doesn't support pythonic properties yet.) e.g.: NumberOfReaders= ComputedAttribute(getNumberOfReaders) But AFAIK, ComputedAttributes don't support write methods. So client code can't write "someArticle.NumberOfReaders += 1". But then, you wouldn't be able to do that with a SQL-based solution either. -- Paul Winkler http://www.slinkp.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] non-undoable storage
I have a couple hundred Articles (class instances) in my ZODB. Most instances are 200 kB, some are much larger. One of the Article properties is Number of times the article was read. Any increment causes ZODB to grow by the size of the given instance, due to the fact that ZODB will append a new version of the whole 200 kB or 2MB instance just because a single byte was changed. Consequently ZODB grows several hundred MB in a single day even if no new article is added. This calls for some form of non-undoable storage. One possibility is to move the "NumberOfReaders" attribute from ZODB to my SQL server. Not a problem, but I'm not sure what is the best way to maintain connection between ZODB instance (it can appear at different places in ZODB directory structure and it can be moved from place to place with Cut and Paste in ZMI) and SQL table. Connection means SQL key column. Instance ids cannot be used as a SQL key, because they are nonunique - each folder has a sequence of instances numbered 1...x. So there are over ten instances named "1". Instance addresses = URLs could be used but I would have to write my own methods / interfaces for moving Articles in the directory structure to maintain the connection between ZODB and SQL table.
