I have a requirement to change how the order number are created via creating a new version of the AssignOrderNumber Task. I have been looking through the code and notice that the OrderNumberGenerator gets the seed from the database and then checks against the max order number within the orders table.
Is there a reason for doing this? The incrimination of the seed is with a lock and therefore no two threads should be inside the lock at any one time. Therefore the seed should always be greater than the max order number.
Is there a reason for this for this check?

This provides an extra layer of protection in the event that the WebAppSetting value is out-of-sync. This could happen if an order is added to the database outside of the application. Also, if you have multiple web servers, the lock only works on the current server, allowing for a concurrency problem on high-traffic sites. So again, the extra check should help prevent this. |
