The APIs can be segmented into two conceptual categories: operation based APIs and query based APIs:.
Operation based APIs
Operation based APIs expose many tightly scoped methods that each implement a very specific Hive operation. Such methods usually accept and return strongly typed values appropriate to their respective operation. The implementations of the operations usually target very specific layers or subsystems within Hive and are therefore likely to be efficient in use. However, the outcome of an operation may diverge from that of the equivalent HQL as the different code paths may be invoked in each case. Operation based APIs are used for constructing processes that need to interact in a repetitive, declarative manner and provide a greater degree of compile-time checking.
