Now Zope comes along with the ability to create and persist objects without the need for a relational database. Wooohooo... all my prayers have been answered, or have they?.
Q1. Has anyone tried to build webapplications with large (maybe into the 10's of thousands) numbers of Zope objects?
Yes.
Q2. How much more or less efficient is Zope for storing a piece of data over a traditional relational database ?
That's a pretty loaded question, they all behave differently. ZODB is comparable in 'efficiency'.
Q3 (I'm a newbie here) Can a python external method access Zope objects ? Eg if I create a task object from a ZClass can I then do things with it from a python script?
Yes.
Q4. I think I remember seeing a post about the Zope database being a single large file posing problems with the Linux filesystem.. or was that the windows filesystem.. if so then that could limit Zope's potential in a commercial production enviroment, surely ?? If this is true what have people done to try and get around this, ie archiving objects (however that could occur) etc.. ?
Zope stores its objects in one file. Linux on 32 bit systems has a 2GB file size limiation. -Michel
