Hi Filipa,

Yes, you could have a separate stream per id and have a separate windowed bolt subscribe to the corresponding stream.

The other option is to do the id based grouping  within the windowed bolt each time its "execute" method is triggered with the tuples in the current window.

With regard to the new windowing features of Storm 1.0.0, is it possible to group the windows by  id, so that the events coming from different clients are processed by different windows?

Thank you.
