То есть теперь можно запилить на Lambda фичи, для которых ранее требовались Step Functions.
Steps—The context.step() method adds automatic retries and checkpointing to your business logic. After a step is completed, it will be skipped during replay.
Wait—The context.wait() method pauses execution for a specified duration, terminating the function, suspending and resuming execution without compute charges.
В результате на простых пайплайнах можно получить 2-4 раза экономию по деньгам.
