This PR implements a generalization of ordered aggregation called segmented aggregation, in which the segment-keys split the input rows into segments of consecutive rows with common values for these segment-keys. In other words, the extra keys are not required to be ordered but only to change from one segment to the next. I opted to generalize this way because the extra implementation effort is quite small and the result is useful. -- This is an automated message from the Apache Git Service.
