@ianmcook @westonpace The current implementation of `cumulative_sum` only works on non-nested Arrays and ChunkedArrays of numeric inputs, and performs a running cumulative sum. Looking at the code, it seems that the output of the ChunkedArray is a large Array. [I added comments to JIRA presenting the different behaviors of cumsum for nested inputs for pandas, numpy, and R.](https://issues.apache.org/jira/browse/ARROW-13530?focusedCommentId=17516180&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17516180) What are your thoughts on handling nested types? PS. Most likely this PR will be scoped to include the basic implementation for numeric types and will have follow-up JIRA issues for date/time types and nested inputs. -- This is an automated message from the Apache Git Service.
