aws-documentdb - 为 Amazon DocumentDB 启用更改流

Question

我知道我们可以使用 Mongo shell 启用(或禁用)Amazon Document DB 的更改流。是否可以从 AWS 控制台或 MongoDB 驱动程序启用更改流？

Answer 1

您可以使用modifyChangeStream API 在您的Amazon DocumentDB 集群上启用变更流。使用 mongo shell 启用/禁用变更流 -

//Enable change streams for the collection "foo" in database "bar"
db.adminCommand({modifyChangeStreams: 1,
    database: "bar",
    collection: "foo", 
    enable: true});
    

//Enable change streams for all collections in database "bar"
db.adminCommand({modifyChangeStreams: 1,
    database: "bar",
    collection: "", 
    enable: true});

//Enable change streams for all collections in all databases in a cluster
db.adminCommand({modifyChangeStreams: 1,
    database: "",
    collection: "", 
    enable: true});

要从您的应用程序启用更改流，您可以使用 @krg265 的建议。
