> By storing global operation and throughput thresholds, we could eliminate the
> "many small memtables" problem caused by having many CFs. The global
> threshold would be set in the config file, to allow different classes of
> servers to have different values configured.
> Operations occurring in the memtable would add to the global counters, in
> addition to the memtable-local counters. When a global threshold was
> violated, the memtable in the system that was using the largest fraction of
> it's local threshold would be flushed. Local thresholds would continue to act
> as they always have.
> The result would be larger sstables, safer operation with multiple CFs and
> per node tuning.
