-----------------------------------------
Summary: Adding Dynamic HTTP Headers to Confluent Schema Registry
Requests
Key: NIFI-8936
URL: https://issues.apache.org/jira/browse/NIFI-8936
Project: Apache NiFi
Issue Type: New Feature
Components: Extensions
Affects Versions: 1.15.0
Reporter: Knowles Atchison Jr
The nifi confluent schema registry service does not currently expose any way to
add arbitrary HTTP headers to requests going to the Confluent Schema Registry.
When using Kafka Client infrastructure outside of NiFi when interacting with
the Confluent Schema Registry, the Deserializer is set to be
KafkaAvroDeserialzer.class. This class contains the SchemaRegistryClient from
Confluent.
One feature this client supports is the sending of HTTP Headers to the schema
registry through properties on the client prefixed with "request.header.". This
can be found in AbstractKafkaSchemaSerDeConfig (in Confluent's schema registry
source code).
I propose to add this functionality to the ConfluentSchemaRegistry.
The controller will be updated to take in dynamic properties which will be
validated as 'request.header.*'. These values will then be added to the
requests going out via Jersey if present.
