Yeah, max execution time (and max memory usage) are the main constraints of using Lambda. Corral deals with this by splitting input data into small enough chunks that each chunk can be processed within the timeout -- I exposed options for setting the amount of data that each Lambda function has to process. However, if each data item requires more than 5 min of processing, then corral won't work for you. The "driver" that coordinates the Lambda functions runs locally (not in Lambda), so it doesn't have this constraint.
