3 million queries/second across 16k nodes seems pretty heavy on redundancy?

2100 clusters, 16k nodes, and data is replicated across every node "within a cluster" with nodes placed in different data centers/regions.

That doesn't sound unreasonable, on average. But I suspect the distribution is likely pretty uneven.
