I've never heard of QuestDB until this post, but I very much like what you guys are doing.

InfluxDB 1.x had a chance to be great: the wrote a time series database that used a SQL-like dialect, they had a really nice alerting platform, they had a really nice visiualization tool. Then they abandoned all of that to jump on the hype train of "Write a new programming language!" which was the hot thing like 5 or 6 hype cycles ago. We've _never_ upgraded to their 2.x product because it literally threw away our investment.

I think if you guys get pick up where they departed you'll be tremendously successful.
