Indicate the S3 bucket to store the interim data. 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. There are 4 categories of built-in Redshift data types: Character, Numeric, Datetime and Boolean. 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. If not specified, it uses the default Azure Integration Runtime.įor a full list of sections and properties available for defining datasets, see the datasets article. You can use Azure Integration Runtime or Self-hosted Integration Runtime (if your data store is located in private network). The Integration Runtime to be used to connect to the data store. Mark this field as a SecureString to store it securely, or reference a secret stored in Azure Key Vault. Name of user who has access to the database. The number of the TCP port that the Amazon Redshift server uses to listen for client connections. IP address or host name of the Amazon Redshift server. The type property must be set to: AmazonRedshift The following properties are supported for Amazon Redshift linked service: Property The following sections provide details about properties that are used to define Data Factory entities specific to Amazon Redshift connector. Search for Amazon and select the Amazon Redshift connector.Ĭonfigure the service details, test the connection, and create the new linked service.

Use the following steps to create a linked service to Amazon Redshift in the Azure portal UI.īrowse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then click New: Database Developer Guide Data type differences between Amazon Redshift and supported PostgreSQL and MySQL databases PDF RSS The following table shows the mapping of an Amazon Redshift data type to a corresponding Amazon RDS PostgreSQL or Aurora PostgreSQL data type.

To perform the Copy activity with a pipeline, you can use one of the following tools or SDKs:Ĭreate a linked service to Amazon Redshift using UI

If you are copying data to an Azure data store, see Azure Data Center IP Ranges for the Compute IP address and SQL ranges used by the Azure data centers.

See Authorize access to the cluster for instructions.

If you are copying data to an on-premises data store using Self-hosted Integration Runtime, grant Integration Runtime (use IP address of the machine) the access to Amazon Redshift cluster.

See Use UNLOAD to copy data from Amazon Redshift section for details. I am curious though to see if this can be done in one CREATE TABLE AS query.To achieve the best performance when copying large amounts of data from Redshift, consider using the built-in Redshift UNLOAD through Amazon S3. * ERROR: 42601: syntax error at or near "as" */Įdit: I'm aware that I could do this in two steps by explicitly creating test.table2 with the correct data types and constraints, then doing an INSERT statement using the data in test.table1. It uses automatic compression, allowing Redshift to select the optimal type. * query executes successfully but still creates column2 as VARCHAR(255) and column1 is NULLABLE. Select the optimum data distribution type: For fact tables choose the DISTKEY type. SELECT column1,CAST(column2 AS NVARCHAR(500)) CREATE TABLE test.table1 (column1 INT NOT NULL, column2 VARCHAR(255)) The redshift stl redshift tables which are used for getting data lineage only. In the below example, I'd like to be able to create a copy of table1 with the column column2 as NVARCHAR(500) type rather than VARCHAR(255) and keep the column1 NOT NULL constraint. Metadata for databases, schemas, views and tables Column types associated.

Is there a way to specify data types and keep constraints when doing a Redshift CREATE TABLE AS query?
