The result will be an output table with the result of the join operation Parameters ---------- join_type : str One of supported join types. left_operand : Table or Dataset The left operand for the join operation. left_keys : str or list[str] The left key (or keys) on which the join operation should be performed. right_operand : Table or Dataset The right operand for the join operation. right_keys : str or list[str] The right key (or keys) on which the join operation should be performed. left_suffix : str, default None Which suffix to add to left column names. This prevents confusion when the columns in left and right operands have colliding names. right_suffix : str, default None Which suffix to add to the right column names. This prevents confusion when the columns in left and right operands have colliding names. use_threads : bool, default True Whether to use multithreading or not. coalesce_keys : bool, default False If the duplicated keys should be omitted from one of the sides in the join result. output_type: Table or InMemoryDataset The output type for the exec plan result.
