Doesn't it cause any problem if > there are a big big Data.fs? Not particularly. If you hit the upper limit of your disk or filesystem limits on file size/partition size you can get into trouble. Also, if it gets too big, you may not have enough room to pack (because the old and new Data.fs files must be able to exist simultaneously.) The ZODB can be broken into multiple files if needed. You could also use DirectoryStorage, but some file systems aren't so good at large numbers of files. But there are no Zope-specific problems with a large database, save that building the index (on startup) can take longer if you have lots of objects. --jcc ___ 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 )

Doesn't it cause any problem if there are a big big Data.fs? I am not getting your point? Is it scalability? Running Zope instances with several Data.fs files up 20-30 GB(!) are not uncommon. -aj pgp1DF98JSn1F.pgp Description: PGP signature ___ 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 )

Re: [Zope] Some problem about Data.fs
What I meant is that if there are more and more objects, maybe it cause some problem because there are a big Data.fs. Doesn't it cause any problem if there are a big big Data.fs?

Of course it grows...it's your Data.fs containing all your data. And you have to pack it on a regular basis (Control Panel -> database administration). However, may it cause some hang problem? Why? Or some file system problem may be raised because there are only files named Data.fs.* for storing object. There should be exactly *one* Data.fs file + Data.fs.index + maybe a Data.fs.pack file from the last ZODB packing operation. It may cause some problem if the objects are more and more. Why? Wow! It is amazing if we have a lot of objects storing here. Does anyone have comment or thinking? You have to make interesting why we should think about.
