---------------------------------------
    Resolution: Duplicate

> Move registering and unregistering changelogs to state updater
> --------------------------------------------------------------

>                 Key: KAFKA-14192
>                 URL: https://issues.apache.org/jira/browse/KAFKA-14192
>             Project: Kafka
>          Issue Type: Improvement
>          Components: streams
>            Reporter: Bruno Cadonna
>            Assignee: Nikita Shupletsov
>            Priority: Major
>
> Currently, we register and unregister changelogs when we initialize and 
> close/recycle a task. 
> When we will remove the old code path for restoration and we will only use 
> the state updater, we should consider to move registering and unregistering 
> changelogs inside the state udpater. In such a way, we would put registering 
> and unregistering changelogs in one place and we would only have changelog 
> registered when it is actually needed, i.e., during restoration of active 
> tasks and updating of standby tasks and not during the complete life of a 
> task.
