Fire and forget AWS step function from lambda

I would like to trigger step function async through the lambda (python boto3).

Can we achieve this?

Looking at the below code, it looks like its not async.

client = boto3.client(STEP_FUNCTIONS)
client.start_execution(
    stateMachineArn=DATAPROCESS_STATE_MACHINE,
    name=STATEMACHINE_EXECUTION_NAME,
    input=json.dumps(state_machine_input)
)

Any suggestions or insights would be appreciated.

Triggering the step functions execution (as you did) is async - calling start_execution will not wait until the state machine finish, but returns immediately.

The response specifies only if the state machine execution was triggered successfuly.
