InfluxDB is the best choice for saving telemetry data, it allows to have low latency when dealing with data and a true SQL-like language. The other software of the TICK suite such as Kapacitor, Telegraf, and Chronograf allows us to receive, transform and visualize data with almost 0 lines of code.

When should I use InfluxDB?

InfluxDB is purpose-built for time series data. Relational databases can handle time series data, but are not optimized for common time series workloads. InfluxDB is designed to store large volumes of time series data and quickly perform real-time analysis on that data.

Which is better InfluxDB or Prometheus?

If monitoring is what you're most interested in, Prometheus is your safest bet because of its many integrations and scalable model. If you're more likely to be using a time series database for IoT, sensors, or analytics, then you'll probably want to choose InfluxDB.
