Nate McCall commented on CASSANDRA-688:
---------------------------------------
Great addition! Just a nitpicky documentation issue - the changes in
storage-conf.xml are worded to suggest that only values between 0-1 are
acceptable for RowsCached whereas in the one example the value is 1000 and 10%
in another. Values between 0-1, integers and percentages all appear to work as
expected.
Perhaps changing the comment like so might make it more clear:
