Function

This API is used to obtain task information of the task center.

Learn how to authorize and authenticate this API before using it.
Before calling this API, obtain the required region and endpoint.

Constraints

This API is used to query only asynchronous tasks in the task center within one month.
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.
