Robert Joseph Evans commented on STORM-676:
-------------------------------------------
[~satish.duggana],
The document seems to make since, but it is at a very high level. It says you
have a working prototype for windowing. Could you post something describing
the changes you had to make to the coordinators or how the coordination works
to support the windowing operations. Also an explanation of how the windowed
state will be stored would be very good. I would like to see both the format
and how the bolts communicate the state to the state store. Will there be any
aggregation before writing the state? How will you handle a topology coming
down and a new one with a different parallelism of bolts/spouts coming back up?
I would suspect that it should not be a problem as we can aggregate over the
old parallelism + the new parallelism, but I want to be sure we take that into
account.
