Check the notes provided for the start-index attribute in the documentation: http://code.google.com/apis/base/docs/2.0/reference.html#StandardQueryParams The /items feed returns a maximum of 10k items. There are two ways that I can think of for updating your items: (1) when inserting an item, Base returns an item ID (<atom:id> or <id>). You will store this Base ID attached to the item and then you just update the item when needed (HTTP PUT to http://www.google.com/base/feeds/items/<the_item_id>) (2) you should provide a <g:id> as part of every item (your sku). This g:id has to be unique across your items. Later on, when you insert (HTTP POST to http://www.google.com/base/feeds/items ) an item with the same g:id, this item will override the old one (because you have the same id, therefore must be the same item). You can use this mechanism for updating the entries that changed on your side regularly.
In both approaches, you should track on your side if you have modified an item after the last update to Google Base, and regularly go through these "dirty" items and update them (using one of the approaches I've described above).
