- 4.TSDB A time series database (TSDB) is a software system that is optimized for handling time series data, arrays of numbers indexed by time (a datetime or a datetime range). In some fields these time series are called profiles, curves, or traces.https://en.wikipedia.org/wiki/Time_series_database4
