The Key Generator transformation can create a set of unique identifiers for the rows in a data set. Use the transformation to create sequence ID values for a Match transformation.
The Key Generator transformation includes an option to sort the output data. To maximize performance, do not check this option. To sort the data, pass the output to a Sorter transformation and configure the cache settings on the Sorter.
