为什么sqs v3 php sdk receive_message MaxNumberOfMessages = 10不返回10条消息？

Question

I am retrieving message from a queue created through amazon sqs. There are around 6 messages in my queue. But I can able to retrieve only one message each time. In document they mentioned you can retrieve up to 10 messages. But I am not getting more than one message at a time.

http://docs.aws.amazon.com/aws-sdk-php/v3/api/api-sqs-2012-11-05.html#receivemessage

Here I am setting MaxNumberOfMessages=10 but still I am getting only one message.

Can anyone help me to retrieve all messages?

Answer 1

Could be because of this:

If the number of messages in the queue is small (less than 1000), it is likely you will get fewer messages than you requested per ReceiveMessage call. If the number of messages in the queue is extremely small, you might not receive any messages in a particular ReceiveMessage response; in which case you should repeat the request.
