Class TopicIdAndName

java.lang.Object
org.apache.kafka.common.TopicIdAndName
public class TopicIdAndName extends Object
Represents a Kafka topic with both its globally unique ID and name. Uniqueness and Equality: For this class, both the ID and name together form the complete unique identifier for a topic. Two TopicIdAndName objects are considered to represent different topics if they have different IDs, even if they have the same name. This means that topics with the same name but different IDs are treated as distinct entities, which can occur in scenarios such as: - Topic recreation after deletion (new ID assigned) - Cross-cluster topic references - Historical topic snapshots This class is immutable and thread-safe.
