> I've invoked the `nodetool compact` three times; this occurred after each.
> The node has been up for a couple days accepting writes and has not been
> restarted.
> Here's the server's log since it was started a few days ago:

> Configuration: One node, one keyspace, one column family. ~60 writes/second
> of data with a TTL of 86400, zero reads. Stock cassandra.yaml.
> Keyspace DDL:
> create keyspace jetpack;
> use jetpack;
> create column family Metrics with key_validation_class = 'UTF8Type' and
> comparator = 'IntegerType';
