Another way that we have used timeseries with Redis at Leftronic is ZSETs. The "score" is the timestamp and the key is a string like {"value": 42, "timestamp": 123456789}. That way you can have auto-sorting/replacement/insertion of timeseries points. Including the timestamp in the key is necessary so you can have duplicate values.
