   <pre>I was able to run the DataFusion examples though, despite these test failures.</pre>

   <pre>If these tests really are specific to 64 bit platforms then we could use conditional compilation and only compile them when target_pointer_width == 64.
   
   See [https://doc.rust-lang.org/reference/conditional-compilation.html#target_pointer_width] for more information.</pre>

   <pre>[~nevi_me] [~vertexclique] I'd be interested in your opinions on this one.</pre>

   <pre>[~andygrove] Hi Andy, I don't have raspberry pi at hand. I want to check the compilation problems on ARM asap, target_pointer_width gate might be a good option for it. What version of rpi did you use?</pre>

   <pre>[~andygrove] 64-bit types and offsets would also be a blocker for supporting wasm32.
   
   If someone completes ARROW-9453, perhaps we can gauge from that on what effort it takes to support 32-bit.</pre>
