That is just a sample data, we are going live in Jun and I don't have anything real so far. Right now it's 9.6 and it will be a latest stable available release on the date that we go live.
You need to use your knowledge of the application to come up with some plausible sample data.
What happens when something succeeds? Does it get deleted from the table, or does it get retained but with a certain value of the status column? If it is retained, what happens to the priority and times_failed fields?
The performance of your queuing table will critically depend on that.
If you need to keep it once it succeeds, you should probably do that by deleting it from the queuing table and inserting it into a history table. It is much easier to keep performance up with that kind of design.
