>From a scalar operation perspective, you could of course emulate XOR via AND, OR, and negation. However, you might want to write anyway a java-based UDF to efficiently implement this recursive operator.
Down the road, we can think about a generalization of our existing cumulative operations such as cumsum, cumprod, cummax, to arbitrary cell computations and aggregation functions, which would be useful for quite a number of applications.
