Function Overview

Cloud Data Migration (CDM) is an efficient and easy-to-use batch data integration service. Based on the big data migration to the cloud and intelligent data lake solution, CDM provides easy-to-use migration capabilities and capabilities of integrating multiple data sources to the data lake, reducing the complexity of data source migration and integration and effectively improving the data migration and integration efficiency.

To get started with CDM, buy a cluster that suits your needs, such as binding an EIP to the cluster, restarting the cluster, modifying cluster notifications, and isolating users.

CDM supports two migration modes, and the supported data sources are as follows: 

• Table/File migration in the import of data into a data lake or migration of data to the cloud. For details, see Data Sources Supported by Table/File Migration.

• Entire DB migration in the import of data into a data lake or migration of data to the cloud. For details, see Supported Data Sources in Entire DB Migration.

CDM supports table and file migration between homogeneous or heterogeneous data sources. CDM supports scheduled execution of table/file migration jobs, concurrent extractors of jobs, scheduled backup and restoration of CDM Jobs, environment variables of CDM job parameters and import/export jobs in batches.

You can use the APIs provided in this document to perform operations on CDM, such as creating a cluster and creating a migration job.
