title: Trigger AWS Lambda by cloudwatch and insert record into RDS
body: <p>I've created a lambda to listen to some of the tags of certain logs to extract the info. And the requirement is to insert these records into a DB, for which I'm using RDS. But as lambdas are stateless, every time I need to do a transaction, need to setup the DB connection. So In a situation where multiple records are received by the lambda in high frequency, is this arrangement going to throttle? </p>
  
  <p>If that's the case, then should I use a queue to extract necessary info from the logs and then invoke the lambda?</p>
