577661b712 -Change update strategy. Previous strategy of aggregated update statements acheived the lowest required execution of statements, but required a prepare per execute. This strategy uses a single prepare, though does not reduce execute. One prepare+thousands of executes is cheapare than a few dozen prepares+executes
