Both pipes are experimental. The recycler pipe is considered the more mature one and should be tried in isolation first. The net effect of optimizers in combination depends on the workload. Stepwise experimentation is the way to go forward here. regards, Martin Kersten On 2/7/12 11:44 PM, zack_pcd wrote:

Is it possible to have a mix of these pipe's optimizers so you get the benefit of both? Or are these two pipes incompatible? (recycler_pipe and cracker_pipe)
