> When there is a gap (or say hole) be found in a streaming cube, kylin will try to build a segment for that gap at one time; If the gap is big, it may not be able to finish the building in-memory. So kylin should provide a configurable max-gap-to-fill at the cube level, user can customize that by evaluating the speed that data comes. Then a big gap will be splitted as several small gaps which can be built in sequence.
