Claus Thanks for taking the time to respond to this camel newbie.
The schema registry url is the host & port for the schema registry, which allows the KafkaAvroSerializer (io.confluent.kafka.serializers.KafkaAvroSerializer) to look up the schema used to serialize and deserialise an avro message, to avoid the need to include this information with each message. See http://docs.confluent.io/current/app-development.html#java and http://docs.confluent.io/current/schema-registry/docs/intro.html <http://docs.confluent.io/current/schema-registry/docs/intro.html#> There is another thread on camel-users where some other people have been trying get around the “Schema Registry Url problem” http://camel.465427.n5.nabble.com/Camel-2-17-Kafka-SSL-Producer-and-Consumer-td5779947.html which seems to suggest that the way to achieve this is to implement custom KafkaAvroDeserializer (& by extension also a KafkaAvroDeserializer) in which to pass in the URL of the schema registry, which seems rather complicated, but perhaps this is the only way?
