Hadoop Sqoop efficiently transfers bulk data between Apache Hadoop and structured datastores such as relational databases. Sqoop helps offload certain tasks (such as ETL processing) from the EDW to Hadoop for efficient execution at a much lower cost. Sqoop can also be used to extract data from Hadoop and export it into external structured datastores. Sqoop works with relational databases such as Teradata, Netezza, Oracle, MySQL, Postgres, and HSQLDB. Sqoop does the following to integrate bulk data movement between Hadoop and structured datastores: Import sequential datasets from a mainframe, parallel data transfer, fast data copies, efficient data analysis, load balancing.
