title: Transfer data from json files in S3 to RDS
body: <p>I have many json files located in S3. I need to take each file, extract the relevant information, and insert the data into various tables in mySQL database I have in Amazon RDS. What is the best way to do this? The files are arriving constantly so I need this service to run all the time - taking files, parsing them and inserting data to the database.
  Thanks!</p>
