[jira] [Created] (ARROW-13914) [C++][Python] Optimize type inference when converting from python values

---------------------------------------

             Summary: [C++][Python] Optimize type inference when converting from python values
                 Key: ARROW-13914
                 URL: https://issues.apache.org/jira/browse/ARROW-13914
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Krisztian Szucs


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
