Note: non-SQL nodes are allowed to delete/overwrite both both the incoming and outgoing tables, so do not point them to non-temporary structures. Also they tend to land all columns (losing narrowing optimization), so can be expensive and should be used sparingly. Finally their result can only be used once in a pipeline (else they will try to clobber their own result).

database implementation signature: f_db(db, incoming_table_name, outgoing_table_name, nd) (db being a database handle)
data.frame implementation signature: f_df(data.frame, nd) (NULL defaults to taking from database).
data.table implementation signature: f_dt(data.table, nd) (NULL defaults f_df).
