hi.
You can use SQL API to parse or write the header in the Kafka record[1] if
you are using Flink SQL.

Hi,
You can implement a custom KafkaRecordDeserializationSchema (example
https://docs.immerok.cloud/docs/cookbook/reading-apache-kafka-headers-with-apache-flink/#the-custom-deserializer)
and just avoid emitting the record if the header value matches what you
need.
