queryable state and maintaining all time counts

Hi,

I've been going through various talks on flink's support for queryable
state. Like this talk by Jamie Grier at 2016's Flink forward :

I see how you can easily use this to produce time series data. Eg calculate
the number of events per hour.

But I am wondering how one would go about using it for also maintaining all
time counts. Eg count the number of events since the beginning of time. Is
anybody doing this ? And if so what is your strategy ?
