Subject index file and KeysCached
Date Sun, 05 Dec 2010 13:34:11 GMT
for each sstable, there is an index file, which is loaded in memory to locate a particular
key's offset efficiently.
and for each CF, KeysCached can be set to cache keys' location.
could you pls tell me the difference between the two?
I'm wondering whether it's necessary to set "KeysCached" for a CF or not.
Thanks for your time.
