Why do we need to perform partitioning in Hive? |
|
Answer» Apache HIVE organizes tables into PARTITIONS. Partitioning is the manner in which a table is split into RELATED components depending on the values of APPROPRIATE columns like date, city, and department. Every table in the hive can have one or more than one partition keys to recognize a distinct partition. With the help of partitions, it is effortless to do queries on SLICES of the data. |
