The locations of the source and the destination files in the local filesystem is provided as a first and second arguments to the transformation script. The transformation script is expected to read the data from source, transform it and write the output to the local destination file. The operator then takes over control and uploads the local destination file to S3.

S3 Select is also available to filter the source contents. Users can omit the transformation script if S3 Select expression is specified.
