> For an index build job, if all the new added indexes can be built from their
> existed parent index. No index was built from new created flat table.
> For this case, there won't be any data inconsistency across indexes. And
> there is no need to build a new flat table to serve the stage of index build
> by layer.
> So I think we can skip stage BUILD DICT and stage GENERATE FLAT TABLE for an
> index build job in condition that all new added indexes can be built from
> their existed parent index
