You can modify an index table based on scenario-specific requirements. After you add or modify an index table, you need to update configurations and perform reindexing. Detailed procedure:
1. On the O&M Management page, click Change Index Table.
2. In the Index Schema step, find the index table that you want to manage and click View/Modify in the Actions column.
3. Modify the index table configurations in the index_config_edit version, click Save Version, and then publish the version.
After the version is published, the system automatically generates an index table version named index_config_v4. The version number increments by one each time. Click Next.
4. In the Update Configurations step, configure the Data Source Name, Index Table, Index Table Version, Dictionary Configuration Version, and Destination Cluster parameters. Then, click Next.
5. In the Reindex step, select a data source and click Next.
Scenario in which the Data Source Type parameter is set to MaxCompute
Scenario in which the Data Source Type parameter is set to API and the Data Source parameter is set to No data found.
Scenario in which the Data Source Type parameter is set to API and the Data Source parameter is set to Restore Data from Index
If the Data Source Type parameter is set to API, you must retain the data in the current full index version. For more information, see Restore data from an index.
The timestamp configuration must meet the verification rules. You cannot enter a point in time after the API data source is added.
After you start reindexing, you are redirected to the Change History page. You can view the reindexing progress on the Data Source Changes tab.
The index table can be queried online immediately after the reindexing operation is complete.
