Alpha Diallo updated FLINK-31428:
---------------------------------
Description:
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.
