[jira] [Created] (ARROW-13939) how to do resampling of arrow table using cython

krishna deepak created ARROW-13939:
--------------------------------------

             Summary: how to do resampling of arrow table using cython
                 Key: ARROW-13939
                 URL: https://issues.apache.org/jira/browse/ARROW-13939
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++, Python
            Reporter: krishna deepak


Please can someone point me to resources, how to write a resampling code in cython for Arrow table.
 # Will iterating the whole table be slow in cython?
 # which is the best to use to append new elements to. Is there a way i create an empty table of same schema and keep appending to it. Or should I use vectors/list and then pass them to create a table.

Performance is very important for me. Any help is highly appreciated.
