A very common use for asynchronous replicas is to offload long-running
reporting jobs onto the replica so that they don't bog down the master.However, long-running reporting jobs often
requiretemporary tables,
especially if they use some 3rd-party vendor's reporting tool. For
example, the average Microstrategy report involves between 1 and 12
temporary tables.
