Struct polars::prelude::ChunkedArray

pub struct ChunkedArray<T> { /* private fields */ }

ChunkedArray

Every Series contains a ChunkedArray<T>. Unlike Series, ChunkedArray’s are typed. This allows us to apply closures to the data and collect the results to a ChunkedArray of the same type T. Below we use an apply to use the cosine function to the values of a ChunkedArray.

fn apply_cosine(ca: &Float32Chunked) -> Float32Chunked {
    ca.apply(|v| v.cos())
}

If we would like to cast the result we could use a Rust Iterator instead of an apply method. Note that Iterators are slightly slower as the null values aren’t ignored implicitly.

fn apply_cosine_and_cast(ca: &Float32Chunked) -> Float64Chunked {
    ca.into_iter()
        .map(|opt_v| {
        opt_v.map(|v| v.cos() as f64)
    }).collect()
}

Another option is to first cast and then use an apply.

fn apply_cosine_and_cast(ca: &Float32Chunked) -> Float64Chunked {
    ca.apply_cast_numeric(|v| v.cos() as f64)
}

Conversion between Series and ChunkedArray’s

Conversion from a Series to a ChunkedArray is effortless.

fn to_chunked_array(series: &Series) -> Result<&Int32Chunked>{
    series.i32()
}

fn to_series(ca: Int32Chunked) -> Series {
    ca.into_series()
}

Iterators

ChunkedArrays fully support Rust native Iterator and DoubleEndedIterator traits, thereby giving access to all the excellent methods available for Iterators.

fn iter_forward(ca: &Float32Chunked) {
    ca.into_iter()
        .for_each(|opt_v| println!("{:?}", opt_v))
}

fn iter_backward(ca: &Float32Chunked) {
    ca.into_iter()
        .rev()
        .for_each(|opt_v| println!("{:?}", opt_v))
}

Memory layout

ChunkedArray’s use Apache Arrow as backend for the memory layout. Arrows memory is immutable which makes it possible to make multiple zero copy (sub)-views from a single array.

To be able to append data, Polars uses chunks to append new memory locations, hence the ChunkedArray<T> data structure. Appends are cheap, because it will not lead to a full reallocation of the whole array (as could be the case with a Rust Vec).

However, multiple chunks in a ChunkArray will slow down many operations that need random access because we have an extra indirection and indexes need to be mapped to the proper chunk. Arithmetic may also be slowed down by this. When multiplying two ChunkArray's with different chunk sizes they cannot utilize SIMD for instance.

If you want to have predictable performance (no unexpected re-allocation of memory), it is advised to call the rechunk after multiple append operations.

See also ChunkedArray::extend for appends within a chunk.

Implementations

impl<T> ChunkedArray<T> where
    T: PolarsNumericType,
    <T as PolarsNumericType>::Native: Signed, 

pub fn abs(&self) -> ChunkedArray<T>

Convert all values to their absolute/positive value.

impl<T> ChunkedArray<T> where
    T: PolarsNumericType, 

pub fn append(&mut self, other: &ChunkedArray<T>)

Append in place. This is done by adding the chunks of other to this ChunkedArray.

See also extend for appends to the underlying memory

impl<T> ChunkedArray<T> where
    T: PolarsNumericType, 

pub fn extend(&mut self, other: &ChunkedArray<T>)

Extend the memory backed by this array with the values from other.

Different from ChunkedArray::append which adds chunks to this ChunkedArray extent appends the data from other to the underlying PrimitiveArray and thus may cause a reallocation.

However if this does not cause a reallocation, the resulting data structure will not have any extra chunks and thus will yield faster queries.

Prefer extend over append when you want to do a query after a single append. For instance during online operations where you add n rows and rerun a query.

Prefer append over extend when you want to append many times before doing a query. For instance when you read in multiple files and when to store them in a single DataFrame. In the latter case finish the sequence of append operations with a rechunk.

The ArrayRef we indicated with 3. will be updated during iteration. The Series will be pinned in memory, saving an allocation for

1. Arc<..>
2. Vec<…>
