IdleBetween 池未按指定提取消息 [英] IdleBetween pools not pulling Messages as specified

问题描述

我正在以批处理模式消费消息.我想每 250 毫秒从流中提取 8 条消息.

I am consuming messages in batch mode. I wanted to pull 8 messages each 250 ms from stream.

spring:  
  cloud:
    stream:
      kinesis:
        bindings:
          input:
            consumer:
              listenerMode: batch
              idleBetweenPolls: 250
              recordsLimit: 8
      bindings:
        input:
          group: my-group
          destination: stream
          content-type: application/json

我已将大约 100 条消息推送到流中，然后我启动了消费者.

I have pushed around 100 messages on to stream, and I started the consumer.

根据配置，我应该每 250 毫秒提取一次消息.但是轮询器不会每 250 毫秒拉取一次消息.

As per configuration, I am supposed to pull messages each 250 ms. But the poller not pulling messages each 250 ms.

@StreamListener(Sink.INPUT)
  public void receiveMessage(Message<List<byte[]>> messages) {
    log.info("Total received messages: " + messages.getPayload().size());
  }

2019-04-27 12:04:53.817 : Total received messages: 8

我什至没有处理任何事情.它只是日志.

I am not even processing anything at all. Its just log.

每条消息之间的时间超过 250 毫秒.我是不是错过了什么.

The time between each messages are more than 250 ms. Am I missing anything.

推荐答案

250 ms 对于实际用例没有意义.也许您可以将间隔增加到 5 秒并尝试一下.

250 ms is not meaningful for realistic use case. Maybe you could increase interval to 5 second and give a try.
