Function

This API is used to start ECSs in a batch based on specified ECS IDs. A maximum of 1,000 ECSs can be started in one minute.

This API is an asynchronous API. After the batch start request is successfully delivered, a job ID is returned. This does not mean the batch start is complete. You need to call the API by referring to Querying Task Execution Status to query the job status. The SUCCESS status indicates that the batch start is successful.
