Annotation Type AvroSchema

@Retention(value=RUNTIME)
@Target(value={TYPE,PARAMETER,METHOD,FIELD})
@Documented
public @interface AvroSchema

Declares that a Java type should have a specified Avro schema, overriding the normally inferred schema. May be used for classes, parameters, fields and method return types.

This is useful for slight alterations to the schema that would be automatically inferred. For example, a List<Integer>whose elements may be null might use the annotation

@AvroSchema("{\"type\":\"array\",\"items\":[\"null\",\"int\"]}")

since the Nullable annotation could not be used here.
