No. An outer join can be more computationally intensive than an inner join because it needs to process all rows from both tables and include rows that don't have matching entries.

An outer join returns all rows from both tables, with nulls where there's no match.

This results in more data to process, which increases execution time, especially when both Stream and Reference tables have millions of rows.
