Thanks Caoilte!

I faced this issue also. Finally solved by using long polling follow the configuration here: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-long-polling-for-queue.html

Unfortunately, to use long polling, you must create your queue as FIFO one. I tried standard queue with no luck.

And when receiving, need also set MaxNumberOfMessages. So my code is like:

ReceiveMessageRequest receive_request = new ReceiveMessageRequest() .withQueueUrl(QUEUE_URL) .withWaitTimeSeconds(20) .withMaxNumberOfMessages(10);

Although solved, still feel too wired. AWS should definitely provide a more neat API for this kind of basic receiving operation.

From my point, AWS has many many cool features but not good APIs. Like those guys are rushing out all the time.
