Summary

  • In this document, we will discuss about the steps to be followed along with the necessary libraries and code chunks needed to establish the connectivity from R to S3 using aws roles and between R and Redshift using jdbc drivers.
  • In order to append the above file with new set of data (by default the files will be replaced/rewritten), we need to read the entire content into a variable in R and append the dataframe in R session itself and then write back to S3 with the same file name.
  • Actually, it is a workaround to simulate the append scenario on S3 files.
  • Copy all the smaller files from s3 to Redshift using COPY command.
