Well, in that case, it is similar to the situation of hitting the limits of vertical scaling - you'll have to scale out horizontally. You could consider sizing down the number of CPU and RAM you allocate to each task manager, but instead increase their count (and your job's parallelism). It might come with its own downsides, so measure as you go. This might also be problematic if you have significant key skew for some of your key ranges.
