Hi, can you switch you queue to FIFO instead of standard?

FIFO has a built-in mechanism to avoid such duplicates: see https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues-exactly-once-processing.html

More details about this depuplication mechanism at https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/using-messagededuplicationid-property.html
