OpenSearch:Clear data

Usage notes

• Clearing data triggers reindexing.

• This operation clears all documents from the application. This action is irreversible. Proceed with caution.

• If both an online application and an offline application exist, you must delete the offline application before clearing data.

  Note

  After you configure an application and run the first indexing, only an online application exists. If you directly clear data or make other changes to the online application, reindexing is triggered. To ensure the stability of your online application, OpenSearch creates an offline application for all changes. After the changes are applied and indexing is complete, you can test the offline application. After the test passes, you can set it as the online application. This process ensures that application changes are transparent to users.

• To ensure service continuity, clearing data creates a new offline application. This offline application clears its full data. However, if new incremental data is added to the instance during reindexing, the offline application also synchronizes this data.

Procedure

1. Log in to the OpenSearch console.

2. Select the target region and switch to OpenSearch Industry Algorithm Edition.

3. Navigate to the Instance Management page. Find the target instance, expand the More menu, and click Clear All Data. In the dialog box that appears, enter the application name and click Clear. This action triggers reindexing and creates a new offline application.

The dialog box contains an orange warning message: This operation cannot be paused or canceled.
