Overview
From the March 2023 (4.32.1.0) release, the JDBC driver class for Redshift Snap Pack will use the Amazon Redshift driver com.amazon.redshift.jdbc42.Driver as the default driver. This upgrade is backward-compatible; however, the support for the PostgreSQL driver class will end by the November 2023 (4.34 release).
Note:
The new pipelines will use the Redshift Driver as the default driver from the March 2023 release. The existing pipelines will continue to work as expected; if the accounts are configured to use either PostgresQL or Redshift driver the respective driver is used without any issues. SnapLogic will support providing fixes for the issues you might encounter with accounts using the PostgreSQL driver in the Redshift Snap Pack only uUntil November 2023 (4.34 GA release).
After November 2023 (4.34 GA release), SnapLogic will NOT support providing fixes for the bugs that you might face with the accounts using the PostgreSQL driver. Therefore, in such scenarios, you must migrate from the PostgreSQL driver to the Redshift driver.
Migrating to Redshift Driver
To migrate from the PostgreSQL driver to the Redshift driver as the default driver, update the JDBC Driver class name in the Account settings from “org.postgresql.Driver” to "com.amazon.redshift.jdbc42.Driver" in your existing accounts.
