Explain customer serialization and deserialization in Kafka.
In Kafka, message transfer among the producer, broker, and consumers is done by making use of a standardized binary message format. The process of converting the data into a stream of bytes for the purpose of the transmission is known as serialization.
Deserialization is the process of converting the bytes of arrays into the desired data format. Custom serializers are used at the producer end to let the producer know how to convert the message into byte arrays. Deserializers are used at the consumer end to convert the byte arrays back into the message.
