Package io.apicurio.registry.serde

Class SerdeConfig

java.lang.Object
io.apicurio.registry.serde.SerdeConfig
public class SerdeConfig extends Object
Contains all of the Serde configuration properties. These are all the property names used when configuring serde classes in Kafka apps via a Properties object. Serde classes can be used by creating them directly as well, in which case these property names are not relevant.
