------------------------------------
Maybe we could introduce a new scheduling trigger {{PROGRESS}} the percentage
of which the input result partitions have finished to schedule each downstream
consumer task. This {{PROGRESS}} parameter is of range 0~1, and 0 corrresponds
to current {{ANY}} and 1 corresponds to current {{ALL}} respectively. In
practice, it can be configured to about 1 saying 0.8 to balance the speedup
advantage and possible resource deadlock.
