I think you're saying a lot more about Oracle than about Influx :)
I also am using Influx at my company and the experience is not that great, mostly due to it being immature yes. For example, I currently have runaway disk usage and I have no way to know what table is using it. So I have to choose between losing data or continuously increasing storage.
One bit of immaturity I just remembered: InfluxDB does a terrible job of telling you when you've fat-fingered a query. You can select from a series that doesn't exist or reference a tag that doesn't exist inside a 'where' clause, and InfluxDB will happily return 0 results instead of giving an error.
I've spent some time trying to figure out why I'm not getting data, and it turns out that it was because I typoed the name of the series.
