   > I suggest we hold off merging this PR until the Arrow 3.0 release is completed (happening in the next day or two) to minimize the chance we break something right before the release
   
   @alamb thanks for the review! Since there is no direct evidence that this PR can fix something in arrow, it's OK to me to hold off merging this PR.
   
   BTW, I've exploring the cause of `test_struct` test failure for several days, filed several issues, but can't figure out the exact reason. The latest issue is filed and commented at https://issues.apache.org/jira/projects/ARROW/issues/ARROW-11239. It looks like `ArrayRef::slice()` is not bug-free. I suggest you evaluate this problem seriously before the 3.0 release. 
   
   CC @jorgecarleitao I'm glad if you can take time for this possible problem at this weekend, as you said :)
