Hi Yuta,

No, you can't get the same state from different functions. That's not the semantics of state. And these two functions might run in different threads/processes even on different machines.

Hi all

I want to use the same state for multiple times.

stream
.keyBy(0)
.map(new MyRichMapfunction)
...
.keyBy(0)
.map(new MyRichMapfunction2)


In this snippet, I want access the same state in MyRichMapfunction and
MyRichMapfunction2, but I failed in spite of keying the same key.
Is there any way to access the state from other class, or is there a
kind of global state.
