@shibd I have a concern about this pr. After this pr, the process is "topicFuture timeout -> close topic -> remove topicFuture". During the "close topic", client can acquire the timeout response immediately and retry. That means, if topicFuture timeout, client may generate a large amount of retry requests to server. Is seems not very good. I have test and see client retry frequently in log ``` 17:53:05.357 [pulsar-io-32-30] INFO org.apache.pulsar.broker.service.ServerCnx - [[id: 0xce950df8, L:/ip1:6651 - R:/ip2:50384]] Subscribing on topic persistent://test/test/test-partition-0 / test_304_pulsar. consumerId: 43 17:53:05.357 [pulsar-io-32-30] WARN org.apache.pulsar.broker.service.ServerCnx - [/ip2:50384][persistent://test/test/test-partition-0][test_304_pulsar] Failed to create consumer: consumerId=43, Failed to load topic within timeout 17:53:05.472 [pulsar-io-32-30] INFO org.apache.pulsar.broker.service.ServerCnx - [[id: 0xce950df8, L:/ip1:6651 - R:/ip2:50384]] Subscribing on topic persistent://test/test/test-partition-0 / test_304_pulsar. consumerId: 43 17:53:05.472 [pulsar-io-32-30] WARN org.apache.pulsar.broker.service.ServerCnx - [/ip2:50384][persistent://test/test/test-partition-0][test_304_pulsar] Failed to create consumer: consumerId=43, Failed to load topic within timeout 17:53:05.592 [pulsar-io-32-30] INFO org.apache.pulsar.broker.service.ServerCnx - [[id: 0xce950df8, L:/ip1:6651 - R:/ip2:50384]] Subscribing on topic persistent://test/test/test-partition-0 / test_304_pulsar. consumerId: 43 17:53:05.592 [pulsar-io-32-30] WARN org.apache.pulsar.broker.service.ServerCnx - [/ip2:50384][persistent://test/test/test-partition-0][test_304_pulsar] Failed to create consumer: consumerId=43, Failed to load topic within timeout ``` -- This is an automated message from the Apache Git Service.
