@alamb -- I'm taking a look back at this ticket. There has been some changes, and I'm unclear as to long term plans. There is a new [FieldMetadata](https://github.com/apache/datafusion/blob/420a862faa98abdb941f22d6b7c9bd463a51c777/datafusion/expr/src/expr.rs#L448) which only applies to literals and unifies it's handling? What about non-literal fields? How (or is) this related to a consolidation of how schema field metadata is handled? Are we unifying a single wrapper abstraction to handle how merging (e.g. union), precedence (e.g. joins?), aggregates, lists, and/or casting is handled? -- This is an automated message from the Apache Git Service.
