Hi Matthias,

I want to query the current state of the application at real-time. Hence,
state processor API won't fit here. I have the following questions,

* Is the queryable state stable enough to use in production systems ?.

Are there any improvements or development activities planned or going on
with queryable state ? Is  Flink community still supporting queryable state
and suggesting its usage? .



Thanks Jessy
