无法在分区中设置检查点 [英] Unable to set checkpoint in partition

问题描述

我正在尝试使用此示例( https://docs.microsoft.com/zh-cn/azure/event-hubs/event-hubs-node-get-started-send )，但我无法读取未读数据只要.还有一件事，我得到两个不同的错误

I am trying to use this sample (https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-node-get-started-send) but I am not able to read unread data only. One more thing I am getting two different error

1)连接ETIMEDOUT 40.112.242.0:5671

1) connect ETIMEDOUT 40.112.242.0:5671

2)更新检查点时租约丢失

2) lease lost while updating checkpoint

在node js示例中，我无法设置检查点.我也尝试过Azure/azure-sdk-for-js.但是它显示了上面列出的相同错误.

In the node js sample, I am not able to set checkpoints. I have tried Azure/azure-sdk-for-js as well. But it is showing the same error listed above.

当我也运行.netcore示例时，它们运行正常，所以我不明白为什么节点js示例运行不正常?

When I have also run .netcore sample then they are working fine so I am not getting why node js sample is not working fine?

能否请您指导我如何解决此问题，以解决未读的只读数据和新数据?

Can you please guide me on how can fix this issue to read-only unread and new data?

推荐答案

对于node.js，请使用以下代码设置检查点，它对我而言效果很好:

For node.js, please use the code below to set checkpoint, it works well at my side:

const { EventProcessorHost, delay } = require("@azure/event-processor-host");

//your eventhub name
const path = "myeventhub"; 

//your azure storage connection string
const storageCS = "DefaultEndpointsProtocol=https;AccountName=xx;AccountKey=xx;EndpointSuffix=core.windows.net";

//your eventhub namespace connectionstring 
const ehCS = "Endpoint=sb://xxx.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=xxx"

//your blob storage container name
const storageContainerName = "test6";

async function main() {
  // Create the Event Processo Host
  const eph = EventProcessorHost.createFromConnectionString(
    EventProcessorHost.createHostName("my-host"),
    storageCS,
    storageContainerName,
    ehCS,
    {
      eventHubPath: path
    }

  );
  let count = 0;
  // Message event handler
  const onMessage = async (context/*PartitionContext*/, data /*EventData*/) => {
    console.log(">>>>> Rx message from '%s': '%s'", context.partitionId, data.body);
    count++;

    return await context.checkpoint();
  };
  // Error event handler
  const onError = (error) => {
    console.log(">>>>> Received Error: %O", error);
  };
  // start the EPH
  await eph.start(onMessage, onError);
  // After some time let' say 2 minutes
  await delay(120000);
  // This will stop the EPH.
  await eph.stop();
}

main().catch((err) => {
  console.log(err);
});

我可以看到在blob容器中检查点设置正确:

And I can see the checkpoint is set correctly in blob container:
