I was trying to understand that if auto.create.topics.enable=true then how
KafkaProducer first creates the topic and sends messages to it.
What I saw:
private Future<RecordMetadata> doSend(ProducerRecord<K, V> record, Callback
method in KafkaProducer.java.
What I failed to get:
When getting metadata for topic using
ClusterAndWaitTime clusterAndWaitTime =
line, I am failed to locate the path where we don't have any metadata for
the topic i.e. topic doesn't exist and according to
"auto.create.topics.enable=true" KafkaProducer invokes createTopic before
sending the record.
It works flawlessly with clients so it must be coded somewhere. I also saw
MockProducerTest.java but unable to locate.
I am a newbie so please forgive for any stupidity here.
