create()

static std::shared_ptr<preprocessed_table> cudf::experimental::row::equality::preprocessed_table::create ( table_view const &  table, rmm::cuda_stream_view  stream  )

static

Factory to construct preprocessed_table for use with row equality comparison or row hashing.

Sets up the table for use with row equality comparison or row hashing. The resulting preprocessed table can be passed to the constructor of equality::self_comparator to avoid preprocessing again.

Parameters

table	The table to preprocess
stream	The cuda stream to use while preprocessing.

Returns

A preprocessed table as shared pointer
