OBS

OBS works as the data source and data storage system for DLI, and delivers the following capabilities:

  • Data source: DLI provides an API for you to import data from corresponding OBS paths to DLI tables.

    For details about the API, see Resource-related APIs > Table-related APIs > Importing Data in the Data Lake Insight API Reference.

  • Data storage: You can create OBS tables on DLI. However, such tables only store metadata while data content is stored in corresponding OBS paths.

    For details, see Creating an OBS Table Using the DataSource Syntax and Creating an OBS Table Using the Hive Syntax in the Data Lake Insight SQL Syntax Reference.

  • Data backup: DLI provides an API for you to export the data in DLI to OBS for backup.

    For details about the API, see Resource-related APIs > Table-related APIs > Exporting Data in the Data Lake Insight API Reference.

  • Query result storage: DLI provides an API for you to save routine query result data on OBS.

    For details about the API, see "SQL Job related APIs" > "Exporting Query Results" in Data Lake Insight API Reference.
