Message queue monitoring refund task batch process

Last tutorial I introduced how to execute multiple queue tasks at one time through batch processing , For this batch scenario , If we don't know the current processing progress, we will always panic ： When can the refund task in the queue be completed ？ Will there be any errors in the processing process ？ For these questions , today , Let's take a look at how to monitor the batch processing of queue tasks , It has been successfully processed in batch 、 Notify related personnel in case of failure .

Batch execution progress

First , In the process of execution , We can get the execution progress of the refund task batch through the following code 、 Remaining tasks 、 Failed tasks and whether to cancel ：

Notify the organizer when successful

If you want to notify the relevant personnel after the batch is successfully executed , You can pass before executing batch processing  then  Callback to define , Here we will send an email notification to the meeting organizer ：

Notify the organizer if it fails

and JavaScript Asynchronous programming in is similar , If batch execution fails , We can follow  then  Callback through  catch  The callback notifies the meeting organizer when it fails ：

Notify organizer when finished

Last , We can also go through  finally  Callback defines the business logic after batch processing , Whether batch processing succeeds or fails , Will execute this code block ：

summary ：

The above is How to monitor the batch processing of queue tasks , It has been successfully processed in batch 、 The code needed in the process of notifying related personnel in case of failure , And in different situations, we can better contact relevant personnel to check .
