[jira] [Created] (ARROW-7941) [Rust] Logical plan should refer to columns by name not index

Andy Grove created ARROW-7941:
---------------------------------

             Summary: [Rust] Logical plan should refer to columns by name not index
                 Key: ARROW-7941
                 URL: https://issues.apache.org/jira/browse/ARROW-7941
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust, Rust - DataFusion
    Affects Versions: 0.16.0
            Reporter: Andy Grove
            Assignee: Andy Grove
             Fix For: 1.0.0


I made a mistake in the design of the logical plan. It is better to refer to columns by name rather than index.

Benefits of making this change:
 * Allows for support for schemaless data sources e.g. JSON
 * Reduces the complexity of the optimizer rules
