> Previously cube segments in one cube are not allowed to overlap with each
> other. This constraint to more intuitive and simple to maintain. This
> constraint makes cube segments immutable, which is acceptable in batch cubing
> scenarios.
> In streaming cubing scenarios, however, there may exist late coming data due
> to upstream latencies. It's best we can still consume those late data rather
> than simply ignore it. To accomplish this we have to relief the above
> constraint.
