title: Flink share state between processElement1 and processElement2 in KeyedCoProcessFunction?
body: <p>I use <code>KeyedCoProcessFunction</code> to enrich main datastream with enrichment stream
  In order to do that I plan to use state
  But when I did implementation I noticed that <code>processElement1</code> and <code>processElement2</code> don't share a state</p>
