geniusjoe opened a new pull request, #23577: URL: https://github.com/apache/pulsar/pull/23577
Main Issue: https://github.com/apache/pulsar-client-go/issues/1297 Relative #21890 ### Motivation When multiple consumers with same name are using dlq policies at the same time, prompt will throw below exceptions: ` ERRO[0069] Failed to create DLQ producer dlq-topic="persistent://<tenant>/<namespace>/<topic>-<subscription>-DLQ" error="server error: ProducerBusy: org.apache.pulsar.broker.service.BrokerServiceException$NamingException: Producer with name '-<subscription>-<consumerName>-DLQ' is already connected to topic" ` ### Modifications I think maybe we need to add a random suffix in dlq producer name like: `opt.Name = fmt.Sprintf("%s-%s-%s-%s-DLQ", r.topicName, r.subscriptionName, r.consumerName, generateRandomName()) ` ### Verifying this change - [x] Make sure that the change passes the CI checks.
