Dian Fu commented on FLINK-7129:
--------------------------------
I think we can firstly create a keyed stream of events {{ds1}} and a non-keyed
stream of patterns {{ds2}} and then connect them with {{ds1.connect(ds2)}} to
collocate them. Regarding to {{TwoInputStreamOperator}}, I didn't find any
limitations to support inputs with one keyed and one non-keyed.
