Open-Source Time Series Databases List
I took some time today, to compile a list of open-source Time Series Databases, with “a little” aid of ChatGPT.

From the list I have first-hand experience with Prometheus, Influx, KairosDB, RRDTool.
OpenTelemetry
So far I know, that Prometheus and InfluxDB do support ingesting data with OpenTelemetry, and the process has been straight-forward.
I am looking at trying to trying Cortex, VictoriaMetrics and TimescaleDB for some experiments with OpenTelemetry. Please let me know in the comments, if you have experience with any of this solutions as OpenTelemetry storage backend.
