non-undoable storage
by Milos Prudek 18 Apr '05

18 Apr '05

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. Is there an obvious elegant solution that I am missing? -- Milos Prudek

Hi, I would like to know the reason why tal:attributes adds an extra newline for each generated tag attribute. This just makes generated HTML bigger... Thanks.

looking for advice to fine-tune large AT migration
by Gerry Kirk 16 Apr '05

16 Apr '05

Hi, I've got about 120K objects in my plone site, and I need to migrate from AT 1.3 alpha to the latest AT. I tried it last night, and the first step, migrating schemas, took all night. There is still the catalogs and references to migrate. I was quite conservative with transactions. I was doing a full transaction every 250 objects. Any suggestions on numbers to use for subtransactions and full ones? My box has 3GB RAM and a fast P4 CPU. Thanks, Gerry

Hi again people, I've just read the article about SESSIONS in the upcoming ZOPE Book 2.7. Here, we have ZEO running, and I need to use SESSION and ZEO. I read the article http://www.zope.org/Members/randy/ZEO-Sessions. Isn't there a easy way to do this? I was wondering if I couldn just createa new filestorage entry in the zeo.conf, and add some lines in my zope.conf file. Thanks. Fernando Lujan
