title: AWS Appflow | Trigger lambda
body: <p>I am pulling data from Salesforce using AWS Appflow and it is dumping data into S3. It is creating many files in S3. How can I run lambda only once per Appflow run. In my scenario, lambda is triggering n number of times, where n is the number of files created in S3 per run.</p>
  <p>Note : 1. I can't create 1 file per run.
  2. I am open for any other approach</p>
