-------------------------------------
Summary: Use KafkaProducer without allocating a new ProducerRecord
for each message sent
Key: KAFKA-4846
URL: https://issues.apache.org/jira/browse/KAFKA-4846
Project: Kafka
Issue Type: Improvement
Components: producer
Affects Versions: 0.10.2.0
Reporter: Mikael Ståldal
The KafkaProducer API requires you to allocate a new ProducerRecord for each
record sent. This is unfortunate since some application wants to reduce object
allocations to minimize GC work. This would be useful for Log4j to allow
[garbage free
logging|https://logging.apache.org/log4j/2.x/manual/garbagefree.html] in its
[Kafka
appender|https://logging.apache.org/log4j/2.x/manual/appenders.html#KafkaAppender].
This could be solved by adding a new method with unrolled arguments to
KafkaProducer, like this:
{code}
Future<RecordMetadata> send(String topic, Integer partition, Long timestamp, K
key, V value);
{code}
