We can see from Table 1 that the tuning methods for monitor, analyze, and plan functions are start or stop, while for execute function are start, stop, and tune the execution cost.
Table 1 Tuning an AC Abstract function Triggering Tuning method Monitor Time driven; Tuner driven Start/Stop Analyze Time/monitor driven; Tuner driven Start/Stop Plan Analyzer driven; Tuner driven Start/Stop Execute Planner/analyzer driven; Tuner driven Start/Stop, or tune the execution cost.
The execution cost (function to be minimized) represents the amount of time required to execute the selected suite.
a middleware cost (mc), which depends on the RAM and/or CPU available in the device, where the middleware is installed; this cost is logically composed by two items: a middleware preprocessing cost (mpc), which is the cost of evaluating whether executing the plugin locally or forwarding it to another device and a middleware execution cost (mec), which applies only to a local execution.
Again, poor execution cost England, and this time Wales were able to take the ball from the resulting scrum and boot it into touch to claim a memorable victory.
Fig. 9 The execution cost with different resources.
With improved effectiveness, the MBFL also brings huge execution cost.
If the server query execution cost is lower, the performance of algorithm will be improved.
In such a case, the execution cost will be set to infinity.
And the total execution cost is (Theta (NS)) without considering partitioning and sorting.
Relevant service-level qualities are response time, execution cost, reliability, or availability.
