Windowed Stream Queryable State Support

What is the state of Windowed Stream Queryable State Support?

Is it available in 1.3 or planned for 1.4?

Thanks
Vijay

Hi,

I was wondering that since it is possible to "query the state of an
in-flight window", if it is also possible to make sure we query *every*
window at the proper time. So how to access in flight window state of a
window of a PU from another PU with Queryable State.
I want to query the window state of one PU, from another PU, while both are
in the same window. 

Thanks!

Hi Vijay,

If by “Windowed Stream Queryable State Support” you mean when will Flink allow to query 
the state of an in-flight window, then a version will be available in 1.4 yes.

Cheers,
Kostas
