Lanayx opened a new issue #9327: URL: https://github.com/apache/pulsar/issues/9327
**Describe the bug** Currently topics name only depend on subscription name and not on the topic name (so there is a clash when different consumers work with different topics and same subscription name) [Link](https://github.com/apache/pulsar/blob/branch-2.7/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ConsumerBuilderImpl.java#L123-L124) There is a [duplicate code block](https://github.com/apache/pulsar/blob/branch-2.7/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ConsumerImpl.java#L325-L344) where topic names are generated correctly, but those are not in use since policy is generated at builder time. **To Reproduce** Steps to reproduce the behavior: 1. Setup 2 consumers that listen to different topics, but the same subscription name 2. Enable retry for both 3. See that retry and dead letter generated topics are the same, so there is a messages clash **Expected behavior** Generated topics should be based both on topic name and subscription name (like [here](https://github.com/apache/pulsar/blob/branch-2.7/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ConsumerImpl.java#L335)) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
