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
