Do you run into problems with Lambda's 5-minute maximum execution time for those kinds of operations? I'd like to do something similar to this for both RDS and DynamoDB, but the execution time will often surpass 5 minutes, meaning I'd have to run a Step Functions worker on EC2 or ECS. That opens up a whole bunch of complexity with managing the worker code and its deployment, which I'd rather avoid if possible.
