To DLI

If the destination link of a job is the Link to DLI, configure the destination job parameters based on Table 1.

When you use CDM to migrate data to DLI, DLI generates data files in the dli-trans* temporary OBS bucket. Therefore, you need to grant the account corresponding to the AK/SK the permissions to read and write the dli-trans* bucket and create directories. For details about how to add OBS permission policies, see Adding an OBS Bucket Policy.
