[jira] [Created] (ARROW-15636) PoC for UDFs

Vibhatha Lakmal Abeykoon created ARROW-15636:
------------------------------------------------

             Summary: PoC for UDFs 
                 Key: ARROW-15636
                 URL: https://issues.apache.org/jira/browse/ARROW-15636
             Project: Apache Arrow
          Issue Type: Sub-task
            Reporter: Vibhatha Lakmal Abeykoon


The idea is to do a proof of concept before developing the UDF API or required kernels as a PR. 

This PoC will be looking into a few ideas. 
 * Using Project (ProjectNodeOptions) to execute a simple Python function which serves as a UDF
 * Using Aggregate (AggregateNodeOptions) to execute a simple Python function which servers as a UDF
