Hi @vincentclee, thanks for reaching out.

Currently waiters are not defined for stepfunctions. Our service teams handle the implementation of waiters so that all AWS SDKs can use them consistently. So I’m transferring this issue to our shared SDK repo. I will reach out to the service team with this feature request and update this issue going forward.

Also please note in the describe-execution documentation it says:

This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.

So this may not always be reliable to depend on for your use case.

Hi @vincentclee - the service team added this to their backlog but they don't see it as something they can prioritize in the near future.

However, they did recommend using EventBridge integrations as an alternative: https://docs.aws.amazon.com/step-functions/latest/dg/cw-events.html

Would using EventBridge work for your use case? I'm going to close this issue but can always reopen or add updates here as needed.
