InfluxDB is an open source distributed timing, event, and metrics database.Written in the Go language without external dependencies. Its design goal is to achieve distributed and horizontal scaling expansion.It has three main features:1. Time series (timeseries): You can use time-related functions (such as Max, Min, sum, etc.)2. Metrics (Metric): You can calculate large amounts of data in real time3. Eevents (Event): It supports arbitrary event dataCh

INFLUXDB can process tens of thousands of data per second, saving all of this data in a large amount of storage space, and sometimes we may not need to store all of the historical data, so INFLUXDB introduced a data retention policy (Retention policies), Used to allow us to customize the data retention time.
