At partners last year i think i was in a session where they said there are new tables that dont use the transient journal. not sure if its something new in 16 or if its avalable in 15.10. I cant seem to find anything about them... but i do remember them talking about them. It sounded like a special talbe kind of like a queue table where its defined when built and has special controles.
It's probably the NO LOG option for temporary tables, i.e. only for Volatile or Global Temporary Tables.
