This PR is intended to include the suffixes for join operations.

This seems like a UX concern for producers to handle rather than something that Substrait needs to model. What's the motivation for including it in Substrait?

@cpcloud I am working on the Join feature for Apache Arrow. We got this merged in, but it only includes partial set of features. And currently working on extending the support further [1] [2].

I don't know what a suffix is. The docs update doesn't do a good job of explaining the purpose.

Searching around it seems like this has to do with field naming(?). Substrait plan nodes don't deal with names, only ordinal positions so if that is the purpose of this patch, it seems like there is a misunderstanding of how substrait works.
