Does the nodetool tablestats output line for "Number of keys (estimate)" indicate partition keys or CQL row primary keys (PK)?
We currently don't have doc on this and I couldn't get a solid answer from a quick examination of the code. Since it is an estimate, roughly what is the nature of the estimation? In particular, for a very wide partition with many CQL rows (even millions) is it estimating that as roughly one key or will the number of sstables that the partition spans make it a large number? Thanks. -- Jack Krupansky
