-----------------------------------
Assignee: Arnab Nandy
> Consider to address inconsistency in `StandbyUpdateListener` API
> ----------------------------------------------------------------
>
> Key: KAFKA-20880
> URL: https://issues.apache.org/jira/browse/KAFKA-20880
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Matthias J. Sax
> Assignee: Arnab Nandy
> Priority: Minor
> Labels: needs-kip
>
> Kafka Streams has two state-restore-listeners: `StateRestoreListener` and
> `StandbyUpdateListener`.
> `StandbyUpdateListener#onBatchLoaded()` is the only method that has a
> `TaskId` parameter. It's unclear why we have this inconsitency.
> Technically, `TaskId` should not be relevant, because the listener is for a
> store, not a task, it would fire for all stores for a task. And
> `TopicPartition` and `storeName` are already passed in which is the more
> relevant information.
