> I pushed a uniform random insert workload from a bunch of clients to the 
> point that the vast majority of bloom filters no longer fit in buffer cache, 
> and the compaction had fallen way behind. Thus, every inserted row turns into 
> 40+ seeks (due to non-compact data) and takes 400-500ms. In this kind of 
> workload, the current backpressure (based on memory usage) is insufficient to 
> prevent ridiculously long queues.
