+RocketMQ schema registry is a management platform for Avro schema of RocketMQ 
Topic, which provides a restful interface
+for store, delete, update and query schema. Schema register will generate new 
schema version in every update request.
+Therefore, during schema evolution, the platform supports formatting and 
verification based on specified compatibility
+configurations. By default, seven compatibility policies are supported. 
Schemas can evolve based on a unique subject,
+and each Schema version in the evolution can be individually referenced to 
other subjects. By binding subject to the
+Schema, the New RocketMQ client can send data based on a user-specified 
structure without requiring the user to care
+about the details of serialization and deserialization
 
 It offers a variety of features:
+
 * Handle basic schema management operation including store, query, update, 
delete
 * Encoding / Decoding capacity by user specified serializer / deserializer in 
client
 * Compatibility validate in duration of schema evolution or send/receive
