Keeping performance in mind, what attribute backend type do you choose when creating the EAV attribute?

You are integrating an external system from which products and categories will be synchronized with Magento.

To keep the category tree synchronized, an identifier attribute needs to be added to the catalog_category entity. The identifier value is generated by the external system as an unsigned 3 byte integer and is global in scope. Your code will run many concurrent queries to select categories based on this ID in order to synchronize changes.
