Detailed Description

Function Documentation

tables_equal()

bool cudf::tables_equal	(	table_view const &	left,
		table_view const &	right,
		null_equality	nulls_equal = null_equality::EQUAL,
		rmm::cuda_stream_view	stream = cudf::get_default_stream()
	)

Check if two tables are equal.

Returns true if the input tables have the same number of rows, the same number of columns, matching column types, and every row in left compares equal to the row at the same index in right. Null equality is controlled by nulls_equal. Floating point NaN values compare equal.

Exceptions

cudf::logic_error

if the tables contain EMPTY types.

Parameters

left	The first table to compare
right	The second table to compare
nulls_equal	Flag to denote if null elements should be considered equal
stream	CUDA stream used for device memory operations and kernel launches

Returns

true if the tables are equal, false otherwise
