    :Modify an index table

    Last Updated:Jun 20, 2026

    Modifying an index table involves updating the index schema, configuring the update, and reindexing.

    1. On the O&M Management page, click Modify Index Table.

    2. To modify the index schema, find the target index table and click View/Modify in the Actions column.

    3. Edit index_config_edit. After making your changes, click Save Version, and then publish.

      After the version is published, the system automatically creates a new index version, such as index_config_v4, with an incremental serial number. Click Next.

    4. Configure the update. Select the Data source and Index table, the newly generated index version, the Dictionary configuration version, and the Destination cluster. Click Next.

    5. Select the corresponding data source and click Next.

      If you set Data source type to MaxCompute data source:

      A notification indicates that reindexing generates a new index version that takes effect only after being switched online. This process is billed on a pay-as-you-go basis. You must configure the Data source name, Associated index table, and Data partition/timestamp.

      If you set Data source type to API data source and Data source to empty data: you must configure the timestamp by selecting a date and time.

      If you set Data source type to API data source and Data source to Restore Data from Index: you must configure the Index version and timestamp by selecting a date and time.

      Important

      • If you are using an API data source and want to preserve the data in the current full index version, you can use the Restore data from an index feature.

      • The timestamp cannot be set to a time after the API data source starts receiving data.

    6. After the reindex process begins, the system automatically redirects you to the change history page. You can monitor the reindex progress under Data source changes.

      The reindex pipeline consists of five stages in order: init, trigger, scan, build, and switch. Each completed stage is marked with a green checkmark, while the current stage shows a loading status.

      After the switch stage is complete, the new index is live.
