InfluxDB v2, Getting started. Preparing the migration from version 1.7 February 17, 2020
The migration to InfluxDB v2 will need adjustments, many InfluxDB v1 functionalities are replaced in version 2.

In this article : getting started with InfluxDB v2 and the breaks to manage when scheduling migration from version 1.x InfluQL is replaced by the language Flux, Continuous queries are replaced by tasks. Native support of the protocols Graphite, OpenTSDB… is removed, Telegraf will have to be used. Grafana plugin for Flux is not yet fully ready.
Understanding, installing and using the time series database InfluxDB 1.7 February 7, 2020

The architecture is well designed (measurements retentions, shards) with easy ingestion, natively or through common time series protocols (OpenTSDB, Graphite…). Queries are SQL Like and the reporting is intuitive with Grafana or Chronograf. This introduction to InfluxDB v 1.7 also points out the breaks with the next major version 2.0.
