>             Project: Flink
>          Issue Type: Bug
>          Components: Connectors / Kafka
>    Affects Versions: 1.12.1
>            Reporter: Dominik Wosiński
>            Priority: Minor
>              Labels: auto-deprioritized-major, stale-minor

> Currently, when FlinkKafkaConsumer is restored from savepoint, the following code will handle topics that do not have offsets committed (for example if a new topic was added):
> {noformat}
> if (restoredState != null) { for (KafkaTopicPartition partition : allPartitions) { if (!restoredState.containsKey(partition)) { restoredState.put(partition, KafkaTopicPartitionStateSentinel.EARLIEST_OFFSET); } }{noformat}
>  
> So if we have a KafkaConsumer with topicPattern and the pattern is changed, new topis will always start from earliest offset, even if originally the setting was different.
