SQS connections offer the same settings as S3 connections to define AWS credentials
SQS messages are text only. DSS offers to read or write them as simple text or as JSON
Upon reading, the message’s text is put in the row under a column name, and upon writing, the value of the given column is taken from the row and used as message.
Upon reading, SQS messages are parsed from JSON to fill a row, and conversely, upon writing the fields of the row are grouped in a JSON object
