On the Configure sync settings page, enter the following information:

   • Body column—Provide the name of the document body column within your database table.

2. In Additional configuration – optional, choose from the following options to sync specific content instead of syncing all files:

   • Change-detecting columns—Enter the names of the columns that Amazon Kendra will use to detect content changes. Amazon Kendra will re-index content when there is a change in any of these columns.

   • Time stamps format—Enter the name of the column which contains time stamp formats to use to detect content changes and re-sync your content.

3. Sync mode—Choose how you want to update your index when your data source content changes.

You must run a full sync of your data if your initial sync failed, even if you don't choose full sync as your sync mode option.

   • Full sync: Freshly index all content, replacing existing content each time your data source syncs with your index.

   • New, modified sync: Index only new and modified content each time your data source syncs with your index. Amazon Kendra can use your data source's mechanism for tracking content changes and index content that changed since the last sync.

   • New, modified, deleted sync: Index only new, modified, and deleted content each time your data source syncs with your index. Amazon Kendra can use your data source's mechanism for tracking content changes and index content that changed since the last sync.

4. In Sync run schedule, for Frequency—How often Amazon Kendra will sync with your data source.

5. Choose Next.
