Walter Hernandez commented on KAFKA-16263:
------------------------------------------
Are you referring to:
{{void}}
{{[setGlobalStateRestoreListener|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/KafkaStreams.html#setGlobalStateRestoreListener(org.apache.kafka.streams.processor.StateRestoreListener)]([StateRestoreListener|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/processor/StateRestoreListener.html]
globalStateRestoreListener)}}
Set the listener which is triggered whenever a
[{{StateStore}}|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/processor/StateStore.html]
is being restored in order to resume processing.
{{void}}
{{[setStandbyUpdateListener|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/KafkaStreams.html#setStandbyUpdateListener(org.apache.kafka.streams.processor.StandbyUpdateListener)]([StandbyUpdateListener|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/processor/StandbyUpdateListener.html]
standbyListener)}}
Set the listener which is triggered whenever a standby task is updated
{{void}}
{{[setStateListener|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/KafkaStreams.html#setStateListener(org.apache.kafka.streams.KafkaStreams.StateListener)]([KafkaStreams.StateListener|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/KafkaStreams.StateListener.html]
listener)}}
An app can set a single
[{{KafkaStreams.StateListener}}|https://kafka.apache.org/37/javadoc/org/apache/kafka/streams/KafkaStreams.StateListener.html]
so that the app is notified when state changes.

Set the handler invoked when an internal

There's also this really nice tutorial on the uncaught-exception-handler
