Splits the input record set into multiple streams to allow parallel processing of subsets of the input.
Takes one input, and either a list of field names or a Script expression. Splits the input into any number of outputs, based on hashing the values in the specified fields or expression. For optimal performance, the number of outputs should be odd, preferably a prime number.
Specify a comma-separated list of fields on which to hash.
Specify a Script expression on which to hash.
