massakam commented on issue #81: Support seting topic schema when creating 
producers/consumers
URL: https://github.com/apache/pulsar-client-node/pull/81#issuecomment-603688099
 
 
   > I think this is fine - any user of a schema'd topic is (with this 
implementation) still responsible for serializing to Buffer when sending 
messages or deserializing from Buffer into whatever schema when consuming 
messages.
   
   Once users implement such an application, isn't it a breaking change for 
them to support automatic encoding/decoding?
   ```js
   const buffer = /* object serialization> */;
   producer.send({
     data: buffer,
   });
   ```
   ↓
   ```js
   const obj = {
     key1: "val1",
     key2: "val2",
   };
   producer.send({
     data: obj,
   });
   ```
   If so, I think parts for automatic encoding / decoding should be added in 
this PR or as soon as possible.
