+ get serialized and partition is assigned (if partition is not specified in ProducerRecord).
+ <p>
+ This method is allowed to modify the record, in which case, the new record will be returned. The implication of modifying
+ key/value is that partition assignment (if not specified in ProducerRecord) will be done based on modified key/value,
+ not key/value from the client. Consequently, key and value transformation done in onSend() needs to be consistent:
+ same key and value should mutate to the same (modified) key and value. Otherwise, log compaction would not work
+ as expected.
+ <p>
+ Similarly, it is up to interceptor implementation to ensure that correct topic/partition is returned in ProducerRecord.
+ Most often, it should be the same topic/partition from 'record'.
+ <p>
+ Any exception thrown by this method will be caught by the caller and logged, but not propagated further.
+ <p>
+ Since the producer may run multiple interceptors, a particular interceptor's onSend() callback will be called in the order
+ specified by <a href="../../../../../org/apache/kafka/clients/producer/ProducerConfig.html#INTERCEPTOR_CLASSES_CONFIG"><code>ProducerConfig.INTERCEPTOR_CLASSES_CONFIG</code></a>. The first interceptor
+ in the list gets the record passed from the client, the following interceptor will be passed the record returned by the
+ previous interceptor, and so on. Since interceptors are allowed to modify records, interceptors may potentially get
+ the record already modified by other interceptors. However, building a pipeline of mutable interceptors that depend on the output
+ of the previous interceptor is discouraged, because of potential side-effects caused by interceptors potentially failing to
+ modify the record and throwing an exception. If one of the interceptors in the list throws an exception from onSend(), the exception
+ is caught, logged, and the next interceptor is called with the record returned by the last successful interceptor in the list,
+ or otherwise the client.</div>
