Yufan Sheng commented on FLINK-31428: ------------------------------------- I don't think it's ok to expose the deserialized/serialized values. You can get and modify it only in PulsarXXXXXSchema. The callbacks can use the {{ConsumerInterceptor}} and {{ProducerInterceptor}}, add a trace id in interceptor and access it in Pulsar schema for serialized values. We can add this support and that's enough, I think. > 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 > Priority: Major > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
