What should be the strategy towards InfluxDb v3 with regards to Flux?

I totally agree… I posted a similar concern here: Questions about InfluxDB 3 Enterprise Free Tier for Home users and the future of InfluxDB V2 - #4 by tkohhh

Luckily, I’m just using Influx at home for personal projects. If this was in a work environment for me, I’d be investigating other vendors.

I hope they do the right thing and bring Flux forward into V3 for the reasons you mention.
