[GitHub] [arrow] jorgecarleitao opened a new pull request #8334: ARROW-8205: [Rust] [DataFusion] Added check to uniqueness of column names.
jorgecarleitao opened a new pull request #8334:
URL: https://github.com/apache/arrow/pull/8334
This adds a check, during logical planning, to the uniqueness of column names after a projection and aggregation.
This eliminates the risk that a user creates a wrong logical query by the first column named X when there are two columns named X.
This does not eliminate this risk when the column name is duplicated on a scan.
