[GitHub] [pulsar-client-cpp] shibd opened a new issue, #77: [feature request] C++ and Python client support Dead Letter Topic

shibd opened a new issue, #77:
URL: https://github.com/apache/pulsar-client-cpp/issues/77

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
   
   
   ### Motivation
   
   Current C++ and Python clients do not support the dead letter topics. 
   
   Dead letter topic serves message redelivery, which is triggered by [acknowledgement timeout](https://pulsar.apache.org/docs/concepts-messaging/#acknowledgement-timeout) or [negative acknowledgement](https://pulsar.apache.org/docs/concepts-messaging/#negative-acknowledgement) or [retry letter topic](https://pulsar.apache.org/docs/concepts-messaging/#retry-letter-topic) .
   
   C++ and Python also do not support `acknowledgement-timeout` and `retry-letter-topic`. 
   
   
   ### Solution
   
   1. You can refer to the implementation of java and this [PIP-22](https://github.com/apache/pulsar/wiki/PIP-22%3A-Pulsar-Dead-Letter-Topic).
   2. [PIP-58](https://github.com/apache/pulsar/wiki/PIP-58-%3A-Support-Consumers--Set-Custom-Retry-Delay), here display `retry-letter-topic` trigger send to dead letter topic.
   3. [PIP-124](https://github.com/apache/pulsar/issues/13408) Need support Create init subscription before sending message to DLQ 
   
   ### Alternatives
   
   Can be first implemented `negative-acknowledgement` trigger send to dead letter topic, and then implement `acknowledgement-timeout` and `retry-letter-topic`.
   
   
   ### Anything else?
   
   Reference Java implement PR:
   
   - https://github.com/apache/pulsar/pull/2508
   - https://github.com/apache/pulsar/pull/6449
