The source from which data is imported and the method of data inheritance after reindexing that is triggered by different operations vary based on the data sources that are configured by users. To prevent online issues that are caused by data synchronization failures due to misoperations, this topic describes the details of data import for reindexing.
Operations that trigger reindexing: scheduled reindexing and offline change.
