How to Delete State Machine Executions?

Question

Say I want to keep a StateMachine, but have old Executions which have finished that I don't want to keep around anymore, is there any way to delete those or do they have a TTL? We plan to run quite a few StepFunctions each day, and I was hoping there is a TTL on how long Executions live for once they are finished.

Answer 1

After running many many Step Functions, I can see that AWS keeps 1,000 executions in the console. As far as I can see from the docs & the API, there is no way to delete executions. If you delete your StateMachine, that would also delete the associated executions, but otherwise you would need to wait till you have run 1k more till your StateMachine execution died.

For this reason I would also recommend not using the ability to query executions for monitoring purposes.
