Bowen Li updated FLINK-38876:
-----------------------------
Environment: (was: There isn't a per-cluster/per-stream offset
initializer hook today.
Currently dynamic kafka source uses a single OffsetsInitializer for starting
(and stopping) and it's applied to every cluster. You can see it in
DynamicKafkaSourceBuilder.java (setters + comments "applied to all clusters"),
and it's passed verbatim to each cluster's KafkaSourceEnumerator in
DynamicKafkaSourceEnumerator.java.
However it's common that users will need different initial offsets per cluster)

> Yes. The API is single OffsetsInitializer for starting (and stopping) and
> it's applied to every cluster. You can see it in
> DynamicKafkaSourceBuilder.java (setters + comments "applied to all
> clusters"), and it's passed verbatim to each cluster's KafkaSourceEnumerator
> in DynamicKafkaSourceEnumerator.java.
> There isn't a per-cluster/per-stream offset initializer hook today. If you
> need different initial offsets per cluster, you'd have to run separate
> sources or extend the API to carry cluster-aware initializers.
