[jira] [Created] (FLINK-31428) Add user callbacks to PulsarSource and PulsarSink

Alpha Diallo created FLINK-31428:
------------------------------------

             Summary: Add user callbacks to  PulsarSource and PulsarSink
                 Key: FLINK-31428
                 URL: https://issues.apache.org/jira/browse/FLINK-31428
             Project: Flink
          Issue Type: New Feature
          Components: Connectors / Pulsar
            Reporter: Alpha Diallo


We'd like to add support for user callbacks in {{{{PulsarSource}}}} and {{{}{{PulsarSink}}{}}}. This enables specific use cases such as event tracing which requires access to low level message properties such as message IDs after an event is produced, topic partitions, etc...

The functionality required is similar to {{ConsumerInterceptor}} and {{ProducerInterceptor}} in the Pulsar Client. However, there is a case to be made for adding new APIs that would help avoid the extra cost of ser/deser when getting the message body through the {{Message}} interface in the interceptors.
