Document count—The total number of documents indexed from this data source. This is the total of all documents added to the data source minus the total of all documents deleted from the data source. Use this information to determine how many documents from this data source are included in the index.
-
Document scans—The total number of documents scanned during the sync run. This includes all documents in the data source, including those added, updated, deleted, or unchanged. Use this information to determine if Amazon Kendra is scanning all of the documents in the data source. The number of documents scanned affects the amount charged for the service.
-
Average sync run time in minutes—The average length of time that it takes for a sync run to complete. The time that it takes to sync a data source affects the amount charged for the service.
