   This has big implication on how users configure their memory. Previously, there was one buffer pool per state, now there is one buffer pool total. So it definitely breaks configurations (lowering overall memory usage, but impacting performance).
   
   Is there a concrete reason to add this now, or maybe at some point when we revisit the overall RocksDB configuration model?
