Functions

std::pair<std::unique_ptr<column>, table_view> transpose(table_view const &input, rmm::cuda_stream_view stream = cudf::get_default_stream(), rmm::device_async_resource_ref mr = cudf::get_current_device_resource_ref())

Transposes a table.

Stores output in a contiguous column, exposing the transposed table as a table_view.

Throws:

• cudf::logic_error – if column types are non-homogeneous

• cudf::logic_error – if column types are non-fixed-width

Parameters:

• input – [in] A table (M cols x N rows) to be transposed

• stream – [in] CUDA stream used for device memory operations and kernel launches

• mr – [in] Device memory resource used to allocate the device memory of returned value

Returns:

The transposed input (N cols x M rows) as a column and table_view, representing the owner and transposed table, respectively.
