> Currently we use an extensive set of checks to infer arrow type from python sequences. 
> Last time I checked using asv, the inference part had a significant overhead. 
> We could try other approaches to speed-up the type inference, see comments: https://github.com/apache/arrow/pull/11076#discussion_r702808196
