lhotari opened a new issue, #24294: URL: https://github.com/apache/pulsar/issues/24294
### Search before reporting - [x] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation Currently there's no way to explicly nack messages in Python functions. Use case: This would be useful in using a Python function as a dynamic router that forwards Pulsar messages to multiple other topics. In such a Pulsar function, it would be necessary to configure `autoAck` to `false` and handle acknowledgement only after the forwarded message has be successfully sent to the destination topic. If this fails, the input message should be negatively acknowledged. ### Solution Add negative acknowledgement support to Pulsar Functions Python library and implementation. ### Alternatives _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
