Hopefully this isn't too "pitch"-y, but: if you're looking for a database that's good at time series, will always be open source, and does support scale-out and HA, you might be interested in Apache Kudu (incubating). Feel free to drop by our Slack (http://getkudu-slack.herokuapp.com http://getkudu-slack.herokuapp.com ) if you have any questions.
