Subject [jira] [Commented] (FLINK-7129) Dynamically changing patterns
Date Fri, 18 Aug 2017 12:22:00 GMT

Dawid Wysakowicz commented on FLINK-7129:

Hi [~dian.fu]
Yes the idea was to enable multiple patterns in a single stream with option 2. Unfortunately
while implementing it,  I stumbled across a problem that right now it is impossible to distribute
a Pattern into all instances of operators with all keys. Also there might be a problem that
some keys were not spotted before a new Pattern arrived. 

We could implement a solution that multiple static Patterns are applied to same stream, but
I don't see much advantage over current solution.
