Will change stream work for time series collection in MongoDB
问题
我有一个需求，需要使用更改流来跟踪插入到时间序列集合中的数据。
我尝试创建一个更改流监听器来监听该集合，但它不起作用。
我尝试了这个。这是一个示例代码，可以监听数据库集合中的所有更改，我只是将它们记录在Audit Collection中。
const dbWatch = db.watch();
await dbWatch.on('change', async (next) => {
console.log('Received change event:', next);
resumeToken = next._id;
let insertDocument = getInsertDocument(next);
switch(next.operationType){
case "insert":
insertDocument.Operation = next.operationType;
insertDocument.Description = next.fullDocument;
break;
case "update":
insertDocument.Operation = next.operationType;
insertDocument.Description = next.updateDescription;
break;
}
await AuditColl.insertOne(insertDocument);
});
但这对于时间序列集合不起作用，尽管它们已被插入，我无法接收它们。
我不确定，但我甚至读到它在MongoDB中不受支持。

请确认。

I have a requirement where we need to use change stream to track the data insertions to Time Series collection.
I tried to create a change stream listener to that collection. But it is not working.
I tried this. This is a sample code that can listen to all changes in the database collections, I am just logging them in Audit Collection.
const dbWatch = db.watch();
await dbWatch.on('change', async (next) => {
console.log('Received change event:', next);
resumeToken = next._id;
let insertDocument = getInsertDocument(next);
switch(next.operationType){
case "insert":
insertDocument.Operation = next.operationType;
insertDocument.Description = next.fullDocument;
break;
case "update":
insertDocument.Operation = next.operationType;
insertDocument.Description = next.updateDescription;
break;
}
await AuditColl.insertOne(insertDocument);
});
But this is not working for Time Series Collections, I am unable to receive them even though they are being inserted.
I am not sure but I even read that it is not supported in MongoDB.

看起来我在彻底研究并与相关人员讨论后找到了答案。
截至2023年3月，MongoDB不支持在时间序列集合中使用Change Streams。
