I am running into the infamous

An error occurred (TooManyRequestsException) when calling the DescribeJobDefinitions operation (reached max retries: 4): Too Many Requests

when fanning out to ~100 steps. I see some open PRs about the subject. I am wondering about two things: • Are there config values (max retries, backoff?) that I can play with • Can I catch this issue happening in runner api? I would be happy if the whole run fails immediately (or if I can make it fail). The annoying thing that happens that 2 out of 100 jobs fail to even be registered, the whole job runs and crashes before join because some jobs were not even registered, wasting a lot of time.

TooManyRequestException

for

DescribeJobDefinitions

is unfortunately due to a global AWS limit - a better bet would be to get those limits raised by working with your AWS TAM.
