Refers to an Amazon S3 to-be-used as an interim store by specifying a linked service name of "AmazonS3" type. Property group when using Amazon Redshift UNLOAD. No (if "tableName" in dataset is specified) The type property of the copy activity source must be set to: AmazonRedshiftSource The following properties are supported in the copy activity source section: Property To copy data from Amazon Redshift, set the source type in the copy activity to AmazonRedshiftSource. This section provides a list of properties supported by Amazon Redshift source. Copy activity propertiesįor a full list of sections and properties available for defining activities, see the Pipelines article. If you were using RelationalTable typed dataset, it is still supported as-is, while you are suggested to use the new one going forward. This property is supported for backward compatibility. No (if "query" in activity source is specified) The type property of the dataset must be set to: AmazonRedshiftTable To copy data from Amazon Redshift, the following properties are supported: Property This section provides a list of properties supported by Amazon Redshift dataset.
