sijie opened a new pull request #3766: Support passing schema definition for JSON and AVRO schemas
URL: https://github.com/apache/pulsar/pull/3766
 
 
   *Motivation*
   
   Currently AVRO and Schema generated schemas from POJO directly.
   Sometime people would like to use pre-generated/defined schemas,
   so allow passing in schema definitions would clear the confusions
   on parsing schemas from POJO.
   
   *Modifications*
   
   - Abstract a common base class `StructSchema` for AVRO/PROTOBUF/JSON
   - Standarize on using avro schema for defining schema (we already did that. this change only makes it clearer)
   - Add methods to pass schema definition for JSON and AVRO schemas
   
   *NOTES*
   
   We don't support passing schema definition for PROTOBUF. since we only supported generated messages as POJO
   class for protobuf schema, and we generate schema definition from the generated messages. it doesn't make sense
   to pass in a different schema definition.
