Hi, QuestDB's author here, thanks for posting! I wanted to post this on Show HN, but someone beat me to it!

It's fine to go ahead and post your Show HN when you're ready. Reposts are ok when an article hasn't had significant attention yet—this is in the FAQ: https://news.ycombinator.com/newsfaq.html. Plus a Show HN has additional value.
You should add a comment to the thread giving the backstory of how you came to work on this, and explaining what's different about it. That tends to seed discussion in a good direction. Good luck!
