If you haven’t read them lately, make sure to check out the First Derivatives Q for Gods white paper series for frequent contributions of helpful technical content about using kdb+.

The NYC Kx Meetup was lucky to have two recent authors present their work: James Neill’s paper is An Introduction to Neural Networks with kdb+ and Kevin Holsgrove’s paper is Query Routing for a kdb+ Framework for a Scalable, Load Balanced System.

You can check out their talks on the Kx Systems YouTube channel — don’t forget to subscribe for new content as it becomes available.


kdb+ sym files

Working With Sym Files in kdb+

12 Mar 2019 | , ,

Kdb+ developers often find themselves working on the largest real-time and historical data sets in the world. Managing them involves consuming feeds from multiple sources in parallel, performing in-memory analysis, and storing data on disk for future reference. This technical white paper looks at the sym file, a key component of kdb+ application architecture.

Kdb+/q Insights: Deferred Response

28 Feb 2019 | , , ,

A useful feature in kdb+ version 3.6 is the ability to defer the response to synchronous IPC messages. The value of this becomes more apparent when systems grow and have to handle many users. Deferred response can be considered a more efficient method to serve data to client process
