Correct me @everyone if I'm wrong, but you cannot keep State inside State in that way. So change your signature to: MapState<String, List<...>>

The underlying mechanism wouldn't make sense in this state-inside-state shape.

Hi,

Can anyone please help me on how can I create a MapState of ListState in flink, does flink support the same and if supports, how to declare the descriptor for same state data structure?

If it is not supported, how may I create similar datastructure for state in flink?

Thanks,

Jaswin
