Kx financial engineer, Connor Gervin, gave a talk at a Kx Community NYC Meetup in 2015 that is worth revisiting. Connor described kdb+’s built-in multithreading and multiprocessing capabilities, which are an essential part of every serious kdb+ programmer’s’ toolkit. With these features, programmers can make the best use of multicore hardware when solving increasingly complex problems over ever-expanding datasets.
