Hi Users,

We want to have a real time aggregation (KPI) .

we are maintaining aggregation counters in the keyed value  state  . 

key could be customer activation date and type.

Lot of counters are maintained against that key.

If we want to add one more counter for the existing keys which is in the state backend.  

1.compute the new counter value using database data .

2. group the counter value based on the key   

How do we update the new computed counter to all the existing keyed state?.
