What do you like best about the product?

I had invested a lot of time prototyping a project with another time-series database and was finding a lot of pain points. I decided to give QuestDB a go, and the transition process was really easy and most of the issues I had with the other DB simply went away. Additionally, I gained valuable time when my application starts and has to read current state from the DB... QuestDB delivered my data in half the time the other DB did. I also like the SQL syntax - it's just one less new thing I need to pick up when starting with QuestDB. The free/open source version is great for my purposes.

What do you dislike about the product?

Documentation is pretty good, but I would like to see some more around best practices, particularly with how to design a schema that is optimal for my needs.

What problems is the product solving and how is that benefiting you?

I need to keep track of the current state of about one million data points that change over time. QuestDB had made this simple to do.
