I'm building my own time-series database for some time. https://github.com/akumuli/Akumuli https://github.com/akumuli/Akumuli It's a standalone solution without dependencies on other services or databases. It can handle more than a million data points per second and uses fixed amount of memory to store data on disk but without Graphite's shortcomings (compression is used for everything and timestamps is stored with nanosecond precision). I'm focused mostly on realtime time-series analysis. Akumuli has built-in anomaly detector: EWMA, Holt-Winters and sketch based methods. It can generate different time-series representations, like SAX and PAA. DTW and correlation search is in progress now.
