             Summary: [Python] Create Cython wrappers for sparse array
                 Key: ARROW-4453
                 URL: https://issues.apache.org/jira/browse/ARROW-4453
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Philipp Moritz


We should have cython wrappers for [https://github.com/apache/arrow/pull/2546]

This is related to support for https://issues.apache.org/jira/browse/ARROW-4223 
and https://issues.apache.org/jira/browse/ARROW-4224

I imagine the code would be similar to 
https://github.com/apache/arrow/blob/5a502d281545402240e818d5fd97a9aaf36363f2/python/pyarrow/array.pxi#L748
