Obtaining Information About a Task with a Specified ID
Description
This API is used to obtain information about a task with a specified ID in the task center.
Restrictions
- Currently, only asynchronous tasks in the task center of DDS Community Edition within one month can be queried.
- After a job is generated, it takes several seconds to query the job ID.
- The following asynchronous tasks can be queried: creating an instance (single node, replica set, or cluster), scaling up storage, changing instance class, scaling up a node, restarting a node, performing a primary/standby switchover, changing a private IP address, changing a security group, changing a database port, binding or unbinding an EIP, switching the SSL mode, and changing an AZ, enabling the shard/config IP address, creating a physical backup/snapshot backup, restoration to a new instance using a backup, point-in-time recovery, and database/table-level restoration to a specified time point.
