ModifyDtsJobDuLimit - Data Transmission Service - Alibaba Cloud Documentation Center

Changes the upper limit of DTS units (DUs) for a Data Transmission Service (DTS) task.

DTS allows you to upgrade or downgrade the configurations of DTS instances in a dedicated cluster. You can adjust the resources that are occupied for task execution to dynamically adjust the number of tasks that can be scheduled in the cluster. This way, you can reduce the total number of DUs required for the cluster or release DUs.
Before you change the upper limit of DUs for a DTS task, make sure that sufficient DUs are available.

Debugging
