Redis: Requesting RPOPLPUSH

I’ve had in my past used RPOPLPUSH with the redis feeder. This redis operation comes in handy when you want to send a REST request on some “ID”, and then reuse it in another capacity. Say for example of a bookstore (over simplified).

Queue 1 : books to be added to catalog, gatling consumes and makes a rest call (post) to add the book to the inventory Queue 2 : Holds books that have been added from the above operation. gatling consumes and makes a rest call to get info, search etc.

RPOPLPUSH queue1 queue2 returns the right item from queue1 and inserts it to the left in queue2

I tried adding this to the RedisFeederBuilder but it seems to be very strict w.r.t. to having only one key. (I don’t want to dictate the implementation 😃 ).

PS - RPOPLPUSH is deprecated since 6.2.0 while the scala redis client being used for gatling hasn’t caught up to the newer replacement of RPOPLPUSH aka LMOVE

Thanks a lot! I’m in PTO for one week, I’ll only be able to review when I’ll be back.
