Instead of using ETL Tools, which consume tons of memory on their own system, you will learn how to do ETL jobs directly in and with a database: PostgreSQL.

PostgreSQL Management of External Data (SQL/MED) is also known as Foreign Data Wrapper (FDW). With FDW, there is nearly no limit of external data, that you could use directly inside a PostgreSQL database.

This talk will show you how to use them with examples accessing several data sources.
