Effective in version 10.2.1, you can perform mass ingestion jobs to ingest or replicate large amounts of data for use or storage in a database or a repository. To perform mass ingestion jobs, you use the Mass Ingestion tool to create a mass ingestion specification. You configure the mass ingestion specification to ingest data from a relational database to a Hive or HDFS target. You can also specify parameters to cleanse the data that you ingest.
