- java.lang.Enum<SchemaType>
- - org.apache.pulsar.common.schema.SchemaType

所有已实现的接口:

java.io.Serializable, java.lang.Comparable<SchemaType>
```
@Public
@Stable
public enum SchemaType
extends java.lang.Enum<SchemaType>
```
Types of supported schema for Pulsar messages.
Ideally we should have just one single set of enum definitions for schema type. but we have 3 locations of defining schema types.
when you are adding a new schema type that whose schema info is required to be recorded in schema registry, add corresponding schema type into `pulsar-common/src/main/proto/PulsarApi.proto` and `pulsar-broker/src/main/proto/SchemaRegistryFormat.proto`.
