-----------------------------------
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.
