Yeah, hudi just relies on Avro's schema compatibility in general. From the [specification](http://avro.apache.org/docs/current/spec.html#Schema+Resolution), looks like adding a new field w/o default will error out. ``` if the reader's record schema has a field with no default value, and writer's schema does not have a field with the same name, an error is signalled. ``` -- This is an automated message from the Apache Git Service.
