[GitHub] [arrow] heronshoes opened a new issue, #15289: [Ruby] Return other than @table.raw_records when saving Table to csv

heronshoes opened a new issue, #15289:
URL: https://github.com/apache/arrow/issues/15289

   ### Describe the enhancement requested
   
   #### Target method
   
   Arrow::Table#save
   
   #### Proposed feature
   
   Change return value of Table#save when saving to csv files.
   
   Current code returns `@table.raw_records` (Array of row Arrays). When saving a very big Table, it takes long time to display a large Array with interactive execution such as irb or Jupyter.
   
   When we save as 'arrow' or 'arrows', it simply returns 'true'.
   
   Candidates of return value:
   
   - true
   - self
   - size of Table
   
   #### Impact of this request
   
   It will improve the user experience of interactive execution. The return value of #save is rarely used.
   
   #### Reference of this request
   
   https://github.com/apache/arrow/blob/master/ruby/red-arrow/lib/arrow/table-saver.rb#L174-L176
   
   ### Component(s)
   
   Ruby
