    Description

      Unions represent a collection of results obtained from different branches of computation. The collection is a virtual operation that does not need to execute any tasks. Subsequent operations can conveniently work on the union named data set instead of each individual member of the union. While unions can be implemented efficiently without additional support from Tez, having API support can make it easier and less error-prone to implement.
