Jason Gustafson resolved KAFKA-12154.
-------------------------------------
Resolution: Fixed
> API and implementation for snapshot loading
> -------------------------------------------
>
> Key: KAFKA-12154
> URL: https://issues.apache.org/jira/browse/KAFKA-12154
> Project: Kafka
> Issue Type: Sub-task
> Components: replication
> Reporter: Jose Armando Garcia Sancio
> Assignee: Jose Armando Garcia Sancio
> Priority: Major
>
> Following changes need to be implemented:
> 1. Notify the {{Listener}} when a snapshot is available:
> {code:java}
> interface Listener<T> {
> void handleSnapshot(SnapshotReader<T> snapshot);
> ...
> } {code}
> It is possible that we can reuse the existing {{BatchReader<T>}} but I am not
> sure at this point. Whenever {{handleSnapshot}} is called the implementation
> should assume that the state has been rewound.
>
> 2. Update the {{ListenerContext}} when a snapshot is available:
> {code:java}
> class ListenerContext {
> void fireHandleSnapshot(SnapshotReader<T> snapshot);
> }{code}
