> Key: ARROW-15379
> URL: https://issues.apache.org/jira/browse/ARROW-15379
> Project: Apache Arrow
> Issue Type: Improvement
> Components: JavaScript
> Reporter: Dominik Moritz
> Priority: Major
>
> When we access a row from a table or a struct, we create a proxy for the
> struct. We could improve the performance of these accesses by creating a
> single instance of the proxy and store it on the vector or the data type and
> then reuse that instance.
> This should improve performance.
