The Q Language
Notes from my KX/kdb experience:<p>1.) The in-memory DB .exe was around 500 KB. Imagine that.<p>2.) The Q language syntax, while consistent, is fairly arcane and throwback to decades past.<p>3.) The documentation and driver support is abysmal.<p>4.) It's supposedly extremely fast, but I can't help but wonder if this is a lot of successful PR and hype (like hedge fund bosses insisting on Oracle because it's the only db that 'scales')
