Kafka Message Serializers

How do the messages get created? Using Message Serizliers

Kafka only accepts bytes as input from producers and sends bytes as output to consumers.

Message Serializers means transforming objects/data inot bytes.

They are used on value and key

Key object 123 -> INT -> Key serializer : Integer serializer(smart enough to figure it out ) -> BYTES -> Key : binary

Value object “123healloi” -> STRING -> Value serializer : String serializer(smart enough to figure it out ) -> BYTES -> Value : binary
