Interesting, I would describe it as an SQL client with an easy interface to load column based files. It's built on top of SQLite, which gives an indication of the kind of performance one can expect.
SQLite is pretty fast actually. More problematic is that this uses Electron. Loading a tiny 200-line CSV file took 120MB for me lol
Thanks for the heads up on Electron - I was going to look into onboarding this for our team until that. We have more than enough in the way of crufty crapplications already.
Can it run a proper local server, so that one could connect using an already open browser? (Maybe even remotely.)
