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.

Constraints

RDS jobs are asynchronous. After a job is generated, it takes several seconds to query the job ID.
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 a single or primary/standby DB instance, creating a read replica, deleting a DB instance, changing a single DB instance to primary/standby DB instance, switching a primary/standby DB instance, scaling up storage space, binding or unbinding an EIP, restoring data to a new DB instance, migrating a standby RDS for MySQL DB instance, upgrading a minor version of an RDS for MySQL DB instance, restoring table data to a specified time point for an RDS for MySQL DB instance, and changing an instance class.
