I really wanted to use QuestDB that comes with 8.3 but I had to abandon it for now due to its limitations at the moment. My request to ignition devs, allow us to connect to self hosted external QuestDB database. You already have the code done for it, just give us an option for another historian type that works with QuestDB. Thanks!
