Re: [Zope] Any working experiences in using compression (for storage)?
Hi John Please elaborate. I don't get the relationship between APE and compression issues. Ausum
why not use Ape?

sorry, I should've been more verbose. You're wanting to compress to go around a limit in the size of the data.fs, whereas I think it'd be easier to use a different storage to satisfy your needs: either Ape, or DirectoryStorage, or LocalFS. -- John Lenton (jlenton@gmail.com) -- Random fortune: bash: fortune: command not found

If you are running zope under an early version of python (ie. before python 2.2) then the Data.fs size limit is 2Gb. Here are two potential solutions: (1) Use DBTab to mount multiple .fs files (each one can be up to 2Gb) (2) Install zope with a version of python >= 2.2 - supports 64 bit addressing which enables files up to ~9200 Terabytes - which should be enough to keep you going for a while :) Jonathan

Now I get it. As I said, I need to compress data to fit in a CD catalog, so unless one of other available storages also compress its data internally, there's no point in performing the switch. Thanks for the response, Ausum

oh! I thought you had a CD catalog, and wanted to put it in the db, and were hitting some limit somewhere else :) sorry for the confusion maybe one of the compressed readonly filesystems (e.g., cramfs) will help you? -- John Lenton (jlenton@gmail.com) -- Random fortune: bash: fortune: command not found

I think I was unclear on the concept... My original thought was that you were trying to create a db of content from a bunch of CD's, however from recent follow-up posts I am wondering if you want to distribute a zope-based 'product' on a CD (ie. create a zope-based product, use CD's as the distribution medium, then have an 'installer' take the data from the CD and install the zope 'product' on the user's system)? If this is the case (an ambitious project to be sure - given the various h/w configurations you will have to be installing zope on), how about using DVDs instead of CDs as the distribution medium (4Gb vs ~700Mb)? Also, if this is the case, zope may not be the best 'infrastructure' for your project. If you provide more information as to what you want to accomplish the 'list' may be able to give you better answers (just keep in mind that the list is public and no-one has signed any non-disclosures!)
