3

4

Periodically collects the data and stores it to the databases of DAS.

Advantages:

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

Note:

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

5

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

6

Allows you to perform operations.

Object List

Currently, you can manage instance tables, views, and user-defined types, including opening and viewing objects.

Metadata Collection

In DAS 2.0, the instance metadata is periodically collected at the background and stored in the DAS keyspace. In addition, only structural metadata is collected, and the data in your table is not included to protect your data privacy.

  • Reduces queries on user keyspaces and the impact on the performance of user keyspaces.
  • Improves the search performance for DB instances that contain a large number of tables and supports pagination queries.
  1. On the Keyspace 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, keyspace structure, and table structure.
    • Delete Logs: Deleted logs cannot be recovered. Exercise caution when performing this operation.
