> Currently, when querying state store, it is not clear when the key was updated last. The ides of this JIRA is to make the latest update timestamp for each key-value-pair of the state store accessible.
> For example, this might be useful to
>  * check if a value was update but did not changed (just compare the update TS)
>  * if you want to consider only recently updated keys
