Jungtaek Lim commented on STORM-2027:
-------------------------------------
This is only on storm-starter, and created before Storm officially supports
windowing.
I think we could just replace this to official support windowing.
[~arunmahadevan]
RollingCountBolt in storm-starter implements sliding window internally. Could
you check that we can change this to official windowing feature?
Thanks in advance!
