The Teradata Connector for Hadoop, or TDCH, is a set of APIs and tools that support high-performance parallel bi-directional data movement between Teradata systems and products in the Hadoop ecosystem. TDCH is built atop the MapReduce framework, and utilizes its distributed nature to offer extreme scalability and performance when transferring data between Teradata systems and Hadoop. For more information about TDCH, see the Teradata Connector for Hadoop tutorial.
