Review Comment:
Instead of letting the minion figure out a segment is empty and call
controller API to delete the segment, a more straight forward way is to make
the task generator (running on controller) to directly delete the segment when
it finds there is no valid doc associated with the segment. Another benefit of
this approach is that we can avoid the unnecessary task assignment. See the
comment above
