Weston Pace / @westonpace:
Some of these mappings may get tricky because of differences in how Substrait & Arrow handle options. Note from @bkietz:
Options may only be enumerations. This will get strange with
functions like is_in, where we'll have to require that one argument is a literal
list or something.
Nicola Crane / @thisisnic:
Wasn't sure if this ticket is likely to be divided into subtasks, but if it is, the items that would be highest priority right now for the folks working on the dplyr Substrait producer, (in terms of things that would enable us to run more of our tests) would be the comparison operators. We'd also be happy to contribute/submit PRs for any of these if it's fairly simple to add more once one is already mapped.

This issue was last updated over 90 days ago, which may be an indication it is no longer being actively worked. To better reflect the current state, the issue is being unassigned per project policy. Please feel free to re-take assignment of the issue if it is being actively worked, or if you plan to start that work soon.
Substrait has a number of "stock" functions defined here: https://github.com/substrait-io/substrait/tree/main/extensions
This is basically a set of standard extensions.
We should map these functions to the equivalent Arrow functions.
