The logging here is annoying (and a bit schizophrenic).
Either the keycache loading logging should include as much info as the rowcache loading (time duration, CF/KS names) or it should be a much smaller snippet for both.
The best fix would probably be the line:
INFO XX:XX:XX,XXX completed loading (time; keys) row/key cache for CF in KS.
...which would be a log line per CF per saved key/row cache (with more logging on error).
I don't know if logging that "0 rows (key or row cache) successfully loaded" is worth it either, but I could be swayed by an argument for this.
