+1 for Cassandra and KairosDB. We use Instaclustr to host Cassandra on AWS and do time series data management with Kairos. It's been a hugely scalable, robust system we use ingest about 5B datapoints per day.

Also, Brian (project leader of KairosDB) agreed to a small consulting project for us to help us configure and tune Kairos. He's a very nice guy and was very helpful.
