Time Series

Definitions

1. A sequence of data points indexed by timestamp, typically collected at regular intervals — used for metrics, sensor readings, and financial data, and stored in specialized databases like InfluxDB, TimescaleDB, or Prometheus that optimize for append-heavy writes and time-range queries.

   In plain English: Data that is recorded over time at regular intervals, like temperature readings every minute or stock prices every second.

   Example: "We push CPU and memory metrics as time series to Prometheus and alert when the 5-minute moving average crosses a threshold."
