Parent: ARROW-9423
Issue Type: Sub-task (was: Improvement)
> [Rust] [DataFusion] Optimizer rules should work with qualified column names
> ---------------------------------------------------------------------------
>
> Key: ARROW-10894
> URL: https://issues.apache.org/jira/browse/ARROW-10894
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: Rust - DataFusion
> Reporter: Andy Grove
> Priority: Major
>
> We have a number of optimization rules that deal with column names
> represented by strings.
> In order to support qualified field names in queries we need to update these
> rules to work with a data structure representing optionally qualified column
> names instead.
> Suggested data structure:
> {code:java}
> struct ColumnName {
> qualifier: Option<String>,
> name: String
> } {code}
