   We send the schema definition when a client connect to a broker, so the broker can verify the compatibility of a schema. If we only send the schema version, there is no way for us to verify if the client is using the right schema. Because a client can just provide a random schema number and produce the data with a different schema.
   
   > but in my scenario, the client needs to connect and close connection everytime it consume/produce message. 
   
   Can you explain a bit more about your use case? I would like to understand more why you need to connect and close connection every time it consumes and produce messages. This is an anti-pattern of using Pulsar.
