Peter Gyori commented on NIFI-13745:
------------------------------------
I pushed a new commit:
* both LOCAL and CLUSTER states are available in Python
* the Python StateManager and Scope classes are moved to their own
"componentstate" module.
* Python dictionary can be used from the Python processors to put together the
state itself, and the Python StateManager converts it to a Java HashMap.
> Extend the NiFi Python API with access to StateManager

>
> There are use-cases where it is necessary to store state from Python-based
> processors in NiFi. One such case is creating and using a List* type Python
> processor that needs to store information regarding which items have already
> been listed in previous executions. For that we need to expose the
> StateManager functionality through the Python API.
