A partition is a division of a logical database or its constituent elements into distinct independent parts. Database partitioning is normally done for manageability, performance or availability reasons, or for load balancing.

Partition is widely used in hive. Especially in the ETL domain, most tables have partition attributes, which allow users to continue processing. Partition is more convenient for data management, time partitioning and business partitioning are common.
