Java:Read messages from AWS SQS using ReceiveMessageRequest

Please take a look at this document to understand the difference between short (default) and long polling - https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-short-and-long-polling.html

With short polling, your probability of getting the messages as soon as they arrive are high as explained in the above document.
