[jira] [Created] (ARROW-15585) [C++] Add support for Substrait pushdown projection

Weston Pace created ARROW-15585:
-----------------------------------

             Summary: [C++] Add support for Substrait pushdown projection
                 Key: ARROW-15585
                 URL: https://issues.apache.org/jira/browse/ARROW-15585
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace


The Substrait C++ consumer does not currently handle pushdown projection in the read relation.

For some formats we can push some of this (e.g. column selection) down into the reader.

For the parts we can't push down we can use a project node after the read.
