AWS interestingly launched a managed InfluxDB option under the “Timestream” product this year.
I’ve personally found TimescaleDB to be a much easier to work with platform, even if there is more overhead in defining a schema and enabling compression, etc.
I've been using Influx v1 on a small scaleway instance for a while.
I loved it and the tooling around it as well.
I would get notifications on Telegram if events needing attention happened.
But v3 is still under development so I'll explore Prometheus.
