--------------------------------------
Summary: [Rust] Remove Array.data method in favor of .data_ref to
make performance impact of clone more obvious
Key: ARROW-10683
URL: https://issues.apache.org/jira/browse/ARROW-10683
Project: Apache Arrow
Issue Type: Improvement
Reporter: Jörn Horstmann
The `Array.data()` method is a real performance foot-gun since it involves
cloning an `Arc` which is not obvious to users. When used in innner loops that
can cause big performance impacts. The cloning itself might not be a problem,
but I think it sometimes prohibits other compiler optimizations.
It would be better to remove this method and let users call `array_ref()` and
only clone when really needed.
Most of the current usages seem to be in test assertions which should be easy
to refactor.
