Detailed Description

Function Documentation

std::unique_ptr<table> cudf::from_arrow	(	arrow::Table const &	input,
		rmm::mr::device_memory_resource *	mr = `rmm::mr::get_current_device_resource()`
	)

Create cudf::table from given arrow Table input.

Parameters

input	arrow:Table that needs to be converted to `cudf::table`
mr	Device memory resource used to allocate `cudf::table`

std::shared_ptr<arrow::Table> cudf::to_arrow	(	table_view	input,
		std::vector< column_metadata > const &	metadata = `{}`,
		arrow::MemoryPool *	ar_mr = `arrow::default_memory_pool()`
	)

Create arrow::Table from cudf table input

Converts the cudf::table_view to arrow::Table with the provided metadata column_names.

Exceptions

cudf::logic_error if column_names size doesn't match with number of columns.

Parameters

input	table_view that needs to be converted to arrow Table
metadata	Contains hierarchy of names of columns and children
ar_mr	arrow memory pool to allocate memory for arrow Table
