Obtaining Information About a Task with a Specified ID

Function

This API is used to obtain information about a task with a specified ID in the task center.

Before calling an API, you need to understand the API in Authentication.
Before calling this API, obtain the required region and endpoint.

Constraints

This API is used to query only asynchronous tasks of the last one month in the task center.
Information of the following asynchronous tasks can be obtained: creating single or primary/standby DB instances, creating read replicas, changing single DB instances to primary/standby instances, switching primary/standby DB instances, scaling up storage space, and binding or unbinding EIPs.
