Internally, I would suggest, the future NettyShuffleService will cast SDD to KnownNettySDD if it is not an UnknownSDD: ``` interface SDD { } enum UnknownSDD implements SDD { INSTANCE; } // special singleton stub class KnownNettySDD implements SDD { + ProducerResourceId, ProducerConnection, etc } // later: class AnyOtherSDD implements SDD { other specific shuffle identification } ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
