The Redshift Account no longer fails when a URL is entered in the JDBC URL field and no driver is specified.

Updated the description for S3 Security Token field as follows:

Specify the S3 security token part of AWS Security Token Service (STS) authentication. It is not required unless a particular S3 credential is configured to require it.

• The JDBC driver class for Redshift accounts is bundled with the com.amazon.redshift.jdbc42.Driver as the default driver. This upgrade is backward-compatible. The existing pipelines will continue to work as expected and the new pipelines will use the Redshift Driver as the default driver. SnapLogic will support providing fixes for the issues you might encounter with accounts that use the PostgreSQL driver only until November 2023.
  After November 2023, SnapLogic will not provide support for the issues with the PostgreSQL driver. Therefore, we recommend you to migrate from the PostgreSQL JDBC driver to the Redshift JDBC driver. Learn more about migrating from the PostgreSQL JDBC Driver to the Amazon Redshift Driver. (432patches20101)

• The Instance type option in the Redshift Bulk Load Snap enables you to use the Amazon EC2 R6a instance. This property appears only when the parallelism value is greater than one.

• The Create table if not present checkbox is selected.

• The target table does not exist.

• The table metadata is provided in the second input view.

• The Redshift - Bulk Load and Redshift - Bulk Upsert Snaps now display relevant error message when the AWS security token is expired.

• The Redshift Account now validates correctly when the S3 bucket is blank.

The Redshift accounts support:

• Expression enabler to pass values from Pipeline parameters.

• Security Token for S3 bucket external staging.

• Enhanced the Redshift accounts with the following:

  • Expression enabler to pass values from Pipeline parameters.

  • Support for Security Token for S3 bucket external staging.

• Fixed an issue with Redshift - Execute Snap where the Snap failed when the query contained comments with single or double quotes in it. Now the Pipeline executes without any error if the query contains a comment.
