 Review comment:
   @srkukarni even from primitive types you still should check this condition:
   ```
   compatibilityChecks.getOrDefault(newSchema.getType(), SchemaCompatibilityCheck.DEFAULT)
               .isCompatible(existingSchema.schema, newSchema, strategy);	            .isCompatible(existingSchema.schema, newSchema, strategy)
   ```
