I'm evaluating Greptimedb in prod and while I hate to have a needless component like OTEL-Collector in general, it serves as a read-only gate between the database and the user, so that greptime keeps listening to localhost only, and OTEL-Collector guarantees nobody will write to the database directly.
If it were to give more fine-grained control over write-only access -- would probably just write directly and let it handle the load.
I had a brief look at greptime db. And I'd like to give a little bit of feedback on your funnel. It is clear that your product marketing is targeting business folks rather than developers. That 3 minute vid on the frontpage was next to useless for me. Also very clearly AI.
Having stats is nice but i am not choosing your product because of stats. I actually think greptimedb is exactly what I am looking for, I.e. a humio / falcon logscale alternative. But I had to do some digging to actually infer that.
Your material doesn't highlight what sets you apart from the competition. If you want to target developers which you might not. I dont know.
I want to debug issues using freetext search, i want to be able to aggregate stats i care about on demand.
