Overview

Importing Data to OBS

DLI enables direct access to data stored in OBS for query and analysis, eliminating the need for data migration.

To begin using DLI for data analysis, just import your local data into OBS.

Migrating Data to DLI

To centrally analyze and manage scattered data from various systems, you can utilize migration tools like Cloud Data Migration (CDM) to migrate the data to DLI. Once the migration is complete, you can submit DLI jobs to analyze the data.

CDM supports multiple types of data sources, such as databases, data warehouses, and files. You can configure data source migration tasks on the GUI to enhance the efficiency of data migration and integration.

For details, see Migrating Data from External Data Sources to DLI.

Configuring DLI to Read and Write External Data Sources

If you prefer not to import data into OBS or DLI tables, DLI offers cross-source access capabilities, allowing you to connect to data sources for analysis without the need to migrate the data.
