Compare tables

Matches two streams by a key and splits them three ways.

Two inputs, a and b, matched by one shared key field. Three outputs: in-both (a-side rows whose key appears in b, where the a row wins), only-a, and only-b. With no key set, nothing matches: everything from a goes to only-a and everything from b to only-b.

Properties

• By: the key field both sides share. Required.
