Hi Jincheng,
Thanks for the clarification. Take 'TopN' for example, if I want to write
such kind function,
should I make sure that this function is used with some keys? If I need a
use case to calculate
topn without key, should I write another function or I can reuse previous
one.
I'm not sure ab

Thanks for your questions, I am glad to share my thoughts here:

No, the keys information depends on the implementation
Hi Jark,
> I will call them "local keyed state" because they have different
semantics with keyed state, even if "ListState", "MapState" are keyed state
primitives currently. From the point of my view, this exposes local keyed
state to users.
Actually, it depends on how to understand. From a certa
Hi,
I have a question about the key information of TableAggregateFunction.
IIUC, you need to define
something like primary key or unique key in the result table of
TableAggregateFunction, and also
need a way to let user configure this through the API. My question is, will
that effect the logic of

Hi hequn, Thanks for the reply! I think `withKeys` solution is our better
choice!

Hi Vino,
> The local keyed state we introduced is not exposed to the outside!
I have read your design and know the way how you implement local
aggregation via local keyed state, and how the local keyed state works.
Currently, Flink exposes two basic kinds of state: operator state and keyed
state.
