heronshoes opened a new issue, #15287: URL: https://github.com/apache/arrow/issues/15287
### Describe the enhancement requested #### Target method Arrow::Table#join #### Proposed feature Add an option to select whether to keep or to merge columns in the join result. #### Impact of this request Current behavior is always keep every columns. But it will be convenient to set merge as a default. For example, default in dplyr is `keep = FALSE` (Do not preserve both join keys). #### Reference of this request dplyr-join in R. https://github.com/apache/arrow/blob/master/r/R/dplyr-join.R Join keys are always merged in RedAmber (without an option). https://github.com/heronshoes/red_amber/blob/main/lib/red_amber/data_frame_combinable.rb#L836-L842 ### Component(s) Ruby -- This is an automated message from the Apache Git Service.
