please check [default@unknown] help create column family;
These are default values,  until you explicitly mentioned on CF creation.

Subject: nodetools cfstats question


Hey guys,
I'm using a three node cluster running 0.8.6 with rf of 3. Its a freshly installed cluster
with no upgrade history.
I have 6 cfs and only one of them is written into. That cf has around one thousand keys. A
quick key_range_scan verifies this.
However when I do cfstats, I see the following for this cf.

Number of Keys (estimate): 5248
Key cache capacity: 200000
Key cache size: 99329

What is the definition of these three output values? Both the Number of Keys and Key Cache
size are way over what they should be.
Thanks!
