GitHub user rocketraman created a discussion: Add meta-data to DLQ
**Is your feature request related to a problem? Please describe.** The automatic DLQ is a nice feature, but its lacking any ability to add meta-data to the entry in the DLQ. For example, setting a property like "causalException" with an exception message and stack trace is very useful when looking at the entries in the DLQ and deciding how to handle them. **Describe the solution you'd like** One possible solution may be to allow passing additional properties to the `negativeAcknowledge` method. When an entry is created in the DLQ, the additional props provided would be added to the DLQ message properties. **Alternatives** Manual DLQ handling. Use Pulsar's redelivery count to manually produce to a DLQ topic, along with the necessary meta-data. ~This implies that the redelivery count is populated in the `Message` regardless of the presence of a `DeadLetterPolicy`. I haven't checked whether that is the case or not.~ GitHub link: https://github.com/apache/pulsar/discussions/18840 ---- This is an automatically sent email for dev@pulsar.apache.org.
