Constraints

An IAM user can pass the authentication and access DataArts Studio through an API or SDK only if Programmatic access is selected for Access Type during the creation of the IAM user.
The restrictions on DataArts Catalog APIs are as follows:
- CDM jobs carry large volumes of data, which increases the database load. You are advised to periodically delete unused jobs.
- If a large number of jobs are delivered in a short period, cluster resources may be exhausted.
- CDM is a batch offline migration tool. You are advised not to create a large number of small jobs using CDM.
For the constraints of other modules' APIs, see their API descriptions.
