Description

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.

Contributor guide

Research direction
Investigate the Step Function's state machine definition, specifically the part that iterates over memory configurations. Implement logic to detect when all invocations at a given memory size fail due to timeout, then skip that memory size and continue with larger ones.
