quintagroup.catalogupdater package is intended for extending ZCatalog API
with possiblity to update selected columns only. This package registers
'catalog_updater' utility for that.
To simplify usage of the utility, quintagroup.catalogupdater extends GenericSetup's
ZCatalog XMLAdapter handler, which allows to *update* attribute usage in *column*
tag of *catalog.xml* file.
So, when you add a new column to the catalog, you add catalog.xml file
in some profile with following part::
...
...
This adds *new_column* metadata to the portal_catalog, BUT, this
metadata will be empty untill you rebuild the catalog. To automate
this step you can add 'update="True"' attribute to the tag. And this
will lead to column update after adding. Thus, result usage should look
like this::
...
...
It also supports subtransactions, based on threshold property of ZCatalog.
