default byte[] fromConnectData(String topic, Headers headers, Schema schema, Object value) {
        return fromConnectData(topic, schema, value);
    }
Convert a Kafka Connect data object to a native object for serialization,
potentially using the supplied topic and headers in the record as necessary.

<p>Connect uses this method directly, and for backward compatibility reasons this method
by default will call the {@link #fromConnectData(String, Schema, Object)} method.
Override this method to make use of the supplied headers.</p>
@param topic the topic associated with the data
@param headers the headers associated with the data; any changes done to the headers
       are applied to the message sent to the broker
@param schema the schema for the value
@param value the value to convert
@return the serialized value
