Review Comment:
   Let's make a real schema instead of mocking it. You may use `SchemaBuilder` 
to create it

Review Comment:
   Let's try to serialize it back to `SchemaInfo` because client code might try 
to do that. I think it will throw exception because there is no constructor 
with `@JsonCreator`

Review Comment:
   Consider adding an optional field `uncachedSchemas` for schemas not found in 
cache. We may show this info to the user in the UI. Something like:
   ```
   {
     "schemasInfo": [
       ...
     ],
     "uncachedSchemas": [
       ...
     ]
   }
   ```
