Configures producer options for the Kafka Bridge.

.Example Kafka Bridge producer configuration
[source,yaml,subs="attributes+"]
----
apiVersion: {KafkaBridgeApiVersion}
kind: KafkaBridge
metadata:

spec:

Use the `producer.config` properties to configure Kafka options for the producer as keys.

The values can be one of the following JSON types:

* String
* Number
* Boolean

*Exceptions*

You can specify and configure the options listed in the {ApacheKafkaproducerConfig}.

However, Strimzi takes care of configuring and managing options related to the following, which cannot be changed:

* Kafka cluster bootstrap address
* Security (encryption, authentication, and authorization)
* Consumer group identifier

Properties with the following prefixes cannot be set:

* `bootstrap.servers`
* `sasl.`
* `security.`
* `ssl.` 

If the `config` property contains an option that cannot be changed, it is disregarded, and a warning message is logged to the Cluster Operator log file.
All other supported options are forwarded to Kafka Bridge, including the following exceptions to the options configured by Strimzi:

* Any `ssl` configuration for xref:con-common-configuration-ssl-reference[supported TLS versions and cipher suites]

IMPORTANT: The Cluster Operator does not validate the keys or values of `config` properties.
If an invalid configuration is provided, the Kafka Bridge deployment might not start or might become unstable.
In this case, fix the configuration so that the Cluster Operator can roll out the new configuration to all Kafka Bridge nodes.
