UUID performance in MySQL?

Question

We\'re considering using UUID values as primary keys for our MySQL database. The data being inserted is generated from dozens, hundreds, or even thousands of remote computer

Answer 1

I would assign each server a numeric ID in a transactional manner. Then, each record inserted will just autoincrement its own counter. Combination of ServerID and RecordID will be unique. ServerID field can be indexed and future select performance based on ServerID (if needed) may be much better.
