Cool, this is interesting to me since in our query engine we started from the opposite approach of initially rewriting all IN expressions into comparison and OR and are now introducing specialized kernel for IN. Would be very interested in finding out where the threshold for this optimization is. The benefit is probably bigger for dictionary encoded data and numbers since the string comparison itself will involve some branches. -- This is an automated message from the Apache Git Service.
