Nope.
catalog stuff should be smart enough to figure out whether anything inside
the object has changed during catalog_object. If nothing has changed, none

Cool. Now, in the examples I've seen for interfacing ZCatalog and
ZPatterns, the 'object updated' code does an unindex of the object
and then an index of the object. I copied that pattern for my
"the tables have been updated, reindex everything" code.
So what I should do instead is just do
Will the new data be 'made ready for indexing' before it is compared to

way before it compares it to what is already stored?
Yes.
I'm wondering because it would be significant overhead to 'make a data

There is one problem, the uids stored in the Catalog are based on the path of the

Hi guys,
I've got a problem with ZCatalog. I've got plenty of large

Now, these object have to
