text: Title: Will my data base get lots of connections If there are many requests happen
  Body: <!--- Provide a general summary of the issue in the Title above -->
  ## Context
  I love zappa very much as my team can run the flask application on aws lambda. We don't have to worry our application will be offline someday.
  
  But we are also using SQLAlchemy to connect db in our application. With my understanding lambda will be started every time when a request comes. **Does it mean each application starting will create a new db connection right?** You know, there only few db connections can be consumed in an online database. BTW, if not, how zappa handle the db connection in this situation?
  
  Thanks support team, looking forward your suggestions on this.
