> When describing a keyspace, the CLI produces output for each column family, including the 3 memtable thresholds.
> However, the labels are in the wrong order - the 2nd value is actually the MB, and the 3rd value is actually the minutes:
> describe keyspace MyTestKeyspace;
> ...
> Memtable thresholds: 0.0703125/15/1440 (millions of ops/minutes/MB)
> ...
> update column family MyTestColFam with memtable_throughput = 128;
> describe keyspace MyTestKeyspace;
> ...
> Memtable thresholds: 0.0703125/128/1440 (millions of ops/minutes/MB)
> ...
