Subj:   Re: Serialization of statements to avoid deadlocks
From:   John Graas

IIUC this is a pretty standard enqueue/dequeue strategy and should work OK.

Another approach, depending on the transaction integrity completeness requirements, would be to serialize the small table updates through a queue table: that is, insert the updates into a queue table, and then have a single "SELECT AND CONSUME" statement paired with an UPDATE into the final target table. One can use a stored procedure for this.

This will serialize the updates for the small table without holding-up the rest of the transaction(s).
