= Using a schema from a Kafka producer client

[role="_abstract"]
This procedure describes how to configure a Kafka producer client written in Java to use a schema from {registry}.

.Prerequisites

* {registry} is installed
* The schema is registered with {registry}

.Procedure

. Configure the client with the URL of {registry}. For example:
+
[source,java,subs="+quotes,attributes"]
----
String registryUrl = "https://registry.example.com/apis/registry/v3";
Properties props = new Properties();
props.putIfAbsent(SerdeConfig.REGISTRY_URL, registryUrl);
----

. Configure the client with the serializer, and the strategy to look up the schema in {registry}. For example:
+
[source,java,subs="+quotes,attributes"]
----
props.put(CommonClientConfigs.BOOTSTRAP_SERVERS_CONFIG, "my-cluster-kafka-bootstrap:9092");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, AvroKafkaSerializer.class.getName()); <1>
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, AvroKafkaSerializer.class.getName()); <2>
props.put(SerdeConfig.FIND_LATEST_ARTIFACT, Boolean.TRUE); <3>
----
<1> The serializer for the message key provided by {registry}.
<2> The serializer for the message value provided by {registry}.
<3> The lookup strategy to find the global ID for the schema.
