org.apache.flink.connector.pulsar.sink.writer.topic.register.FixedTopicRegister<IN>

All Implemented Interfaces:

@Internal
public class FixedTopicRegister<IN>
extends Object
implements TopicRegister<IN>

We need the latest topic metadata for making sure the newly created topic partitions would be used by the Pulsar sink. This routing policy would be different compared with Pulsar Client built-in logic. We use Flink's ProcessingTimer as the executor.
