------------------------------------
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.
