I agree there are still places that are N^2 in the number of columns. With @haohuaijin 's great work in https://github.com/apache/datafusion/pull/9595 I think adding an index (perhaps computed on demand) to `DFSchema` might be more tractable to do without causing performance regressions for smaller column counts. It would be great if someone wanted to give that a try -- This is an automated message from the Apache Git Service.
