Sorry aaron, here are the values you requested
RecentBloomFilterFalsePositives = 5;
BloomFilterFalsePositives = 385260;
uptime of the node is three days and a half, more or less

Close: the problem is we don't count *any* true positives *unless*
cache is enabled.
Fix attached to https://issues.apache.org/jira/browse/CASSANDRA-2637.

That reminds me, my false positive ration is stuck at 1.0, so I guess
bloom filters aren't doing a lot for me.
That sounds unlikely unless you're hitting some edge case like reading
a particular row that happened to be a collision, and only that row.
This is from JMX stats on the column family

Hi everyone.
I have a few sstables with around 500 million keys, and memory usage has
grown a lot, I suppose because of the indexes. This sstables are
comprised of skinny rows, but a lot of them. Would tuning index interval
make the memory usage go down? And what would the performance hit be?
