Traits

ChunkAgg

Aggregation operations.

ChunkAnyValue

ChunkApply

Fastest way to do elementwise operations on a ChunkedArray<T> when the operation is cheaper than branching due to null checking.

ChunkApplyKernel

Apply kernels on the arrow array chunks in a ChunkedArray.

ChunkBytes

ChunkCast

Cast ChunkedArray<T> to ChunkedArray<N>

ChunkCompareEq

Compare Series and ChunkedArray’s and get a boolean mask that can be used to filter rows.

ChunkCompareIneq

Compare Series and ChunkedArray’s using inequality operators (<, >=, etc.) and get a boolean mask that can be used to filter rows.

ChunkExpandAtIndex

Create a new ChunkedArray filled with values at that index.

ChunkExplode

Explode/flatten a List or String Series

ChunkFillNullValue

Replace None values with a value

ChunkFilter

Filter values by a boolean mask.

ChunkFull

Fill a ChunkedArray with one value.

ChunkFullNull

ChunkNestingUtils

Utility methods for dealing with nested chunked arrays.

ChunkQuantile

Quantile and median aggregation.

ChunkReverse

Reverse a ChunkedArray<T>

ChunkRollApplyrolling_window

This differs from ChunkWindowCustom and ChunkWindow by not using a fold aggregator, but reusing a Series wrapper and calling Series aggregators. This likely is a bit slower than ChunkWindow

ChunkSet

Create a ChunkedArray with new values by index or by boolean mask.

ChunkShift

ChunkShiftFill

Shift the values of a ChunkedArray by a number of periods.

ChunkSort

Sort operations on ChunkedArray.

ChunkTake

ChunkTakeUnchecked

ChunkUnique

Get unique values in a ChunkedArray

ChunkVar

Variance and standard deviation aggregation.

ChunkZip

Combine two ChunkedArray based on some predicate.

IsFirstDistinctis_first_distinct

Mask the first unique values as true

IsLastDistinctis_last_distinct

Mask the last unique values as true

Functions

_set_check_length^⚠

Meant for internal use. In very rare conditions this can be turned off.
