[jira] [Commented] (ARROW-11206) [C++][Dataset][Python] Consider
hiding/renaming "project"
[ https://issues.apache.org/jira/browse/ARROW-11206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17381571#comment-17381571 ]
Weston Pace commented on ARROW-11206:
-------------------------------------
I think MakeStruct is good and much clearer. This caused plenty of confusion for me as well. I doubt many python uses are using pyarrow.compute.project anyways since they probably specify it via the scanner or dataset options.

> The "project" compute Function is necessary for ARROW-11174. However it is not intended for direct use outside an Expression ([where the correspondence to projection is not immediately obvious|https://github.com/apache/arrow/pull/9131#issuecomment-757764173]) so it may be preferable to do one/more of:
> * rename the function to "wrap_struct" or similar so it does make sense outside Expressions
> * ensure the function is not exposed to python/R bindings except through Expressions
> * remove the function from the default registry
