Generates a functional key from the input columns, by applying different types of algorithms on each column and grouping the computed results in one key, then outputs this key with the input columns.
tGenKey enables you to apply several kinds of algorithms on each input column and use the computed results to generate a functional key, which can be used, for example, to narrow down your data filter/matching results. These algorithms can be key or optional algorithms.
The values returned by the key algorithms will be concatenated, according to the column order in the Key composition table.
In local mode, Apache Spark 2.4.0 and later versions are supported.
