The idea is here is not performance per se, but memory savings. As this is an in-memory join, any saved memory is welcome, as it will increase the chance a given join will fit in memory. Using a boolean array buffer builder makes sense to me to avoid the dependency. -- This is an automated message from the Apache Git Service.
