Set keys in Hadoop conf: You can specify AWS keys using Hadoop configuration properties. You cannot use DBFS mounts to configure access to S3 for Redshift. Spark connects to S3 using both the Hadoop FileSystem interfaces and directly using the Amazon Java SDK’s S3 client. S3 acts as an intermediary to store bulk data when reading from or writing to Redshift. By default, this connection uses SSL encryption for more details, see Encryption. Redshift does not support the use of IAM roles to authenticate this connection.

The Spark driver connects to Redshift via JDBC using a username and password. The following sections describe each connection’s authentication configuration options: You cannot use an External location defined in Unity Catalog as a tempdir location.

See the Encryption section of this document for a discussion of how to encrypt these files. As a result, we recommend that you use a dedicated temporary S3 bucket with an object lifecycle configuration to ensure that temporary files are automatically deleted after a specified expiration period. The data source does not clean up the temporary files that it creates in S3. As a result, it requires AWS credentials with read and write access to an S3 bucket (specified using the tempdir configuration parameter). The data source reads and writes data to S3 when transferring data to/from Redshift. The data source involves several network connections, illustrated in the following diagram: ┌───────┐ Configuration Authenticating to S3 and Redshift If you plan to perform several queries against the same data in Redshift, Databricks recommends saving the extracted data using Delta Lake. Query execution may extract large amounts of data to S3.

Recommendations for working with Redshift Write back to a table using IAM Role based authentication the data source API to write the data back to another table After you have applied transformations to the data, you can use The SQL API supports only the creation of new tables and not overwriting or appending. Write data using SQL: DROP TABLE IF EXISTS redshift_table Read data using SQL: DROP TABLE IF EXISTS redshift_table # Write back to a table using IAM Role based authentication # the data source API to write the data back to another table # After you have applied transformations to the data, you can use option('query', 'select x, count(*) group by x') option('forward_spark_s3_credentials', True) On the other hand, Informatica provides the excellent Redshift connector that works like a charm.External locations defined in Unity Catalog are not supported as tempdir locations. DataStage is not very compatible with the AWS ecosystem. To achieve fast load, you need to build the jobs that do the best Redshift practice ( Loading Data into Redshift), which is not an easy task. Inserting or updating records in Redshift through JDBC (or even ODBC) driver with DataStage is extremely slow. If this option is not ticked, it will lock the table and the job hangs.

To insert or update records, make sure to tick auto-commit in the JDBC stage.

Both can be obtained in the Redshift JBDC driver download page here.ĬLASSPATH: Add the path to the JBDC jar file as in ‘/opt/IBN/InformationServer/Server/DSEngine/3rd-party-drivers/RedshiftJDBC42-1.jar’ĬLASSNAME: Add the class name as in the documentation like ‘’ The config file requires two parameters, ClASSPATH and CLASSNAME. (3) Once the driver is moved to the 3rd-party-drivers folder, you need to edit the nfig file in the DSEngine folder. Mv /tmp/RedshiftJDBC42-1.jar /opt/IBM/InformationServer/Server/DSEngine/3rd-party-drivers/ You need to check your installation path. In this example, I set the installation path as /opt/IBM/InformationServer/Server/DSEngine/.

(2) It is recommended to install the driver to the tmp folder first and move to the 3rd-party-drivers folder. In my experience, the latest version (4.2) was not compatible. (1) Download Redshift JDBC driver from here. In this post, we will discuss how to add Redshift JDBC driver to DataStage server and configure it. In order to use a JDBC driver, you need to download the JDBC and set up the configuration files (see here).
