Data Transfer
When creating a worker invocation you will need to reference a URI to a resource such that jadice flow can access and process the contents of the file. One such possibility is to provide a pre-signed url to a file that is available inside a s3 bucket.

An example for a s3 client that creates a pre-signed url can be found at https://github.com/levigo/s3-java-example
