> Project: Apache Arrow
> Issue Type: Improvement
> Components: JavaScript

> Priority: Major

> A quick experiment
> (https://observablehq.com/@domoritz/performance-of-maps-vs-objects) seems to
> show that object accesses are a lot faster than map accesses. Would it make
> sense to switch to objects in the row API to improve performance?
