Periodically collects metadata such as databases, tables, and fields of the DB instance and stores the data to the databases of DAS.


  • Reduces queries on user databases and the impact on the performance of user databases.
  • Improves the search performance for DB instances that contain a large number of tables and supports pagination queries.


Only structural metadata is collected, which means that user's table data is not included.


Database management consists of the following functional modules: object list and metadata collection.


Allows you to perform operations.

Object List

Currently, you can manage DDM instance tables, such as creating, querying, and modifying objects.

For details on how to manage tables, see Table Management.

Metadata Collection

In DAS 2.0, metadata of a DB instance such as databases, tables, and files can be automatically collected and stored in the DAS database. In addition, only structural metadata is collected, and the data in your table is not included to protect your data privacy.

  • Metadata collection can reduce database queries which may affect the database performance.
  • Metadata collection also improves the search performance for DB instances that contain a large number of tables and supports pagination queries.
  1. On the Database Management page, click the Metadata Collection tab.
  2. On the displayed page, click Collect to start the collection. You can also stop the collection or view the collection details.

    • Clear the collected data: Clear the collected metadata, database structure, and table structure.
    • Delete Logs: Deleted logs cannot be recovered. Exercise caution when performing this operation.
