-------------------------------------------
Assignee: Tzu-Li (Gordon) Tai
> Update Python SDK to implement new invocation protocol
> ------------------------------------------------------
>
> Key: FLINK-20268
> URL: https://issues.apache.org/jira/browse/FLINK-20268
> Project: Flink
> Issue Type: Sub-task
> Components: Stateful Functions
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Major
> Fix For: statefun-2.3.0
>
>
> The Python SDK should be updated to implement the new protocol introduced by
> FLINK-20265.
> Users should be able to declare states the Python function uses, and with
> information, the Python SDK {{RequestReplyHandler}} can then match on the
> provided states values in invocation requests against the declared states of
> a target function:
> Proposed API:
> {code}
> @functions.bind(
> typename="example/greeter",
> states=[StateSpec("seen_count")])
> def greet(context, greet_request: GreetRequest):
> state = context.state("seen_count").unpack(SeenCount)
> ...
> {code}
