My resume about the topic.
The internal workings of a Kafka producer can be described as follows:
1. The Kafka producer sends messages to a partition using a ProducerRecord object that contains information such as the topic name, the partition to which the message should be sent, and the key and value of the message. hash(key)%num_partition
2. Before sending the message, the producer must serialize it into an appropriate format for storage and transmission. This can be done using a custom serializer or by using one of Kafka's built-in serializers.
3. Once the message is serialized, the producer must determine the partition to which the message should be sent. This can be done using a hashing function that takes the message key and the total number of partitions to determine the appropriate partition.
4. The message is then stored in a buffer waiting to be sent. Multiple messages can be stored in the buffer before being sent as a batch.
5. The producer can specify parameters such as maximum wait time (linger.ms) and maximum batch size (batch.size) to control when messages are sent.
6. If sending the message fails for any reason, the producer can either retry sending the message or retry sending the entire batch of messages.
7. If sending the message succeeds, the producer receives information about the message such as the partition offset, timestamp, and other metadata.
Very good job buddy !
