When you run a task configured for pushdown optimization, the task converts the transformation logic to an SQL statement. The task sends the SQL statement to the database, and the database executes the SQL statement.
You work for a rapidly growing data science organization. Your organization develops software products to analyze financials, building financial graphs connecting people profiles, companies, jobs, advertisers, and publishers. The organization uses infrastructure based on Amazon Web Services and stores its data in Amazon Redshift, a petabytescale data warehouse. The organization plans to implement a business intelligence service to build visualization and perform real-time analysis. Therefore, you need to port the vast amount of data stored in Amazon Redshift to the business intelligence service. You can use Amazon Redshift V2 Connector to read data from Amazon Redshift. To read this large amount of data, you can use source pushdown for the ODBC connection type. Using the ODBC connection type with pushdown optimization enhances the performance.
