Review Comment:
@jackye1995 I don't think we need a separate API actually, we are already
given the list of paths. We can still do it lazily by basically using the
previous approach and constructing the bucket/key from the path and keeping
track of when the objects for a bucket hits a certain batch size. It's just
that using the Tasks framework in its current state becomes infeasible since it
operates on a list and also will wait for completion. We want to just submit
the batch deletion and move on, and then at the very end check the statuses of
all those tasks. So using the underlying executor service fits that pattern.
Let me know what you think.
