The store with name "stateStoreName2" could be a view on top of the store with name "stateStoreName", in which case each time we query stateStoreName2, we would, on the fly, compute the result of the filter on values actually stored in the first store. Alternatively, "stateStoreName2" could in itself be materialised, i.e., contain all the results obtained from the filtering. Materialising all Ktables with a state store name could be expensive, however it is a straightforward to implement and could be a good V1. A subsequent JIRA could do an optimization in V2.
