MapWithState is also very useful.
I want to calculate UV in real time, but "distinct count" and "multiple
streaming aggregations" are not supported.
Is there any method to calculate real-time UV in the current version?

Could you please tell me how to use the approximate count distinct? Is there
any docs?
Thanks

Hi
I want to use window operations. However, if i don't remove any data, the
"complete" table will become larger and larger as time goes on. So I want to
remove some outdated data in the complete table that I would never use.
Is there any method to meet my requirement?
Thanks!
