@dongjoon-hyun @holdenk My understanding is different from what you said above. It sounds like the metadata is not available for TimeWindow expression when the function `name(alias: String)` copies the metadata to `explicitMetadata`. Thus, we do not set it when calling the APIs in `Column`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
