-----------------------------------
Resolution: Won't Fix
Nothing to do right now.
> [R] Disallow expressions that depend on order
> ---------------------------------------------

> Key: ARROW-13779
> URL: https://issues.apache.org/jira/browse/ARROW-13779
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Neal Richardson
> Assignee: Neal Richardson
> Priority: Major
>
> Because in the current ExecPlan, sorting is only done in the end (in a sink
> node), we can't sort the data and then do an operation that depends on
> sorting (like cumsum) without first calling compute(). (This is probably not
> yet a concern because don't seem to have any kernels that require order.)
