> 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.
