Module transform 

Low-level array data abstractions.

Provides utilities for creating, manipulating, and converting Arrow arrays made of primitive types, strings, and nested types.

MutableArrayData

Efficiently create an ArrayData from one or more existing ArrayDatas by copying chunks.

_MutableArrayData 🔒

A mutable ArrayData that knows how to freeze itself into an ArrayData. This is just a data container.

Enums

Capacities

Define capacities to pre-allocate for child data or data buffers.

Functions

build_extend 🔒

build_extend_dictionary 🔒

Builds an extend that adds offset to the source primitive Additionally validates that max fits into the the underlying primitive returning None if not
