In our production system we have relatively big tables with up to 500 GB size and we therefore are in the need of acceptable performance for flashback versions queries on these tables.
In a 22.214.171.124 test database we can see that flashback versions query does not execute the full table scan on the FBDA enabled table in parallel whereas in a 126.96.36.199 database this FTS is executed in parallel.
