title: How to run a AWS Lambda after 2 hours
body: <p>I have 2 Lambda, The first Lambda for loading data into my GBQ, And the second Lambda need to be run after that 2 hours to check the data on GBQ. 
  I have investigated it but seems like we can schedule using Rate or Cron, but I want to run the second Lambda only once.
  Is there another way to do it? Thank you.</p>
