Using Int PK instead of GUID for large table data sets
<p>On every good team I've workd on, we've (the leads and architects) stayed away from utilizing GUIDs for authentication and userIDs just because they are especially for an e-commerce site very under-performing in terms of performance vs. just a PK Int.  At least that was the consensus in addition to a pain to work with.</p>

<p>How can I use Int Ids but for large data sets and still get past the uniqueness issue (running out of unique Ids) without using GUIDs?</p>
