# StartDataSourceSyncJob
<a name="API_StartDataSourceSyncJob"></a>

Starts a synchronization job for a data source connector. If a synchronization job is already in progress, Amazon Kendra returns a `ResourceInUseException` exception.

Re-syncing your data source with your index after modifying, adding, or deleting documents from your data source respository could take up to an hour or more, depending on the number of documents to sync.
