Spring Cloud SQS 轮询

Question

I'm using Spring Cloud to consume an AWS SQS. I would like to control the number of polls by setting up an interval between these requests, but I can't find any option to do this.

I'm thinking that using the long polling it's not necessary to control the poll interval. It is that true?

Thank you!

Answer 1

是的，如果您使用长轮询，您将保持连接打开，直到您收到事件，并且您将在它发布时接近它。

You can use WaitTimeSeconds to achieve what you want. Here is AWS documentation - http://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ReceiveMessage.html

The duration (in seconds) for which the call waits for a message to arrive in the queue before returning. If a message is available, the call returns sooner than WaitTimeSeconds.

This one is an optional parameter, so if you don't pass it then it is 0 seconds
