The target describes the Hive or HDFS target where you want to ingest the source tables from the relational database.
You specify different target properties depending on the scenario that you select in the specification definition. If you configure the specification to ingest data from a relational database to Hive, you configure a Hive connection and Hive table properties to define the target. If you configure the specification to ingest data from a relational database to HDFS, you configure an HDFS connection and an ingestion directory to define the target.
The mass ingestion solution ingests all data to the target. The mass ingestion solution does not provide the option to append data that has been recently updated. Each time that you run the mass ingestion specification, the existing data in the Hive or HDFS target is deleted and replaced with the data configured in the ingestion job.
