This is part of a larger body of work I would like to do to DataFusion to make it more efficient and idomatic Rust. See https://issues.apache.org/jira/browse/ARROW-11689 for more context. The theme is to make the plan and expression rewriting phases of DataFusion more efficient by avoiding copies This particular PR avoids deep cloning `Expr`s when building up new exprs. While this is technically a backwards compatible change, given there was only a single place in the datafusion codebase that needs to be updated, I think the impact was minimal. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
