lookupTopicAsync

                                                                          org.apache.pulsar.common.naming.TopicName topicName,
                                                                          boolean authoritative,

Lookup broker-service address for a given namespace-bundle which contains given topic. a. Returns broker-address if namespace-bundle is already owned by any broker b. If current-broker receives lookup-request and if it's not a leader then current broker redirects request to leader by returning leader-service address. c. If current-broker is leader then it finds out least-loaded broker to own namespace bundle and redirects request by returning least-loaded broker. d. If current-broker receives request to own the namespace-bundle then it owns a bundle and returns success(connect) response to client.

Parameters:

pulsarService -

topicName -

authoritative -

clientAppId -

requestId -

Lookup broker-service address for a given namespace-bundle which contains given topic. a. Returns broker-address if namespace-bundle is already owned by any broker b. If current-broker receives lookup-request and if it's not a leader then current broker redirects request to leader by returning leader-service address. c. If current-broker is leader then it finds out least-loaded broker to own namespace bundle and redirects request by returning least-loaded broker. d. If current-broker receives request to own the namespace-bundle then it owns a bundle and returns success(connect) response to client.
