Neville Dipale commented on ARROW-4854:
---------------------------------------
Note to whomever implements this, it's better to not conditionally check the
data type and limit/slice based on it. We can wait for ARROW-4853 then
implement a single slice function:
{code:java}
pub fn limit(array: &ArrayRef, num_elements: usize) -> Result<ArrayRef> {
Ok(array.slice(9, num_elements))
}
{code}
> [Rust] Use Array Slice for limit kernel
> ---------------------------------------

> Key: ARROW-4854

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

> Reporter: Neville Dipale
> Priority: Minor
>
> We currently reconstruct an array when taking a limit from it, we can improve
> performance by using slice from ARROW-3954
