> to do the cube building, there is complex join and error handling logic.
> The new implement leverages the ForkJoinPool from JDK, the event split logic

> main thread. Cuboid task and sub-tasks are handled in fork join pool, cube
> results are collected
> async and can be write to output earlier.
