Enhancing Your kdb+/q Toolkit: Real World Examples of Adverbs

12 Apr 2017 | , , , ,

Nuša Žnuderl's latest blog post uses five real-world examples to demonstrate how kdb+/q coders can improve their results by using adverbs and not using looping constructs. Long-term the benefit is vastly improved performance from doing things in the “q way.” In her blog Nuša writes: "Similar to the English language, adverbs in q augment operations to allow an application on lists. They make code shorter, clearer and almost always more efficient than the alternative loopy modus operandi – all of which are qualities that differentiate code written by proficient q users from the rest."

Kx 1.1 billion taxi ride benchmark highlights advantages of kdb+ architecture

Stellar performance in third-party benchmarks is a tradition at Kx, and now we can add a new benchmark to the list, the taxi ride benchmark developed by Mark Litwintschik. This latest benchmark queries a 1.1 billion New York City taxi ride dataset. Our results were over four orders of magnitude faster than any other CPU technology and comparable to GPU-based code.
