描述

The step function kept failing on the lowest memory option that I provided. This was due to a timeout on the lambda. Either the powertuning step function should also increment timeout (not ideal) or it should recognize if every execution on a particular memory amount fails, it is not enough memory and proceed with the other values. I have achieved similar functionality before when using parallel states. Moreover, this greatly decreases the value of the tool because it is hard to implement in automation if I need to remove all of the lower memory values in order to achieve reliability of the step function.

研究方向
Examine the Step Function state machine definition in the repository (likely in `functions/state machine.asl.json`). Understand how execution results are processed for each memory value. The issue suggests adding logic to detect when all executions for a given memory value fail due to timeout and skip that value. Review the Lambda function that evaluates results and consider how to implement this check, possibly using a parallel state or error handling.
