Andy Grove updated ARROW-7941:
------------------------------
Description:
It should be possible to build a logical plan using colum names rather than
indices since it is more intuitive. There should be an optimizer rule that
resolves the columns and replaces these unresolved columns with column indices.
was:
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
> [Rust] [DataFusion] Logical plan should support unresolved column references
