Workarounds

  1. 95% success Store the payload in S3 and send the S3 reference in the SQS message 
    Use amazon-sqs-extended-client-lib for automatic S3 offloading

    Sources: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-s3-messages.html

  2. 85% success Review the message — reduce unnecessary data fields or use a more compact format 
    Switch from JSON to a more compact format, or remove redundant data

Dead Ends

Common approaches that don't work:

  1. Compressing the message with gzip 50% fail

    Adds complexity; consumer must decompress; base64 encoding increases size by 33%

  2. Splitting the message into parts 55% fail

    Requires a reassembly mechanism; complex and error-prone
