Thanks Jonathan, using mysql as an id sequence generator definitely is a good options. One thing though, does using sequential ids defeat the purpose of random partitioner?
Those are 2 of the 3 options (the other one being, continue to
generate incrementing IDs either by continuing to use mysql solely for
that purpose, or by using another system like redis for that).
