In the latest in an ongoing series of kdb+ technical white papers published on the Kx Developer’s site, Kx engineer Peter Lyness has written about how the Java API for kdb+ can be used to enable a Java program to interact with a kdb+ process.

Peter’s paper explores the API itself, how it is structured, and how it might be included in a development project. Examples are provided for core use cases for the API in a standard setup. Particular consideration is given to how the API facilitates subscription and publication to a kdb+ ticker plant process, a core component of any kdb+ tick capture system.

The examples presented form a set of practical templates complementary to the primary source of information on These templates can be combined and adapted to apply kdb+ across a broad range of problem domains and they are available on GitHub.

What defines a great collaboration? Kx’s Chief Revenue Officer Pat Brazel writes in this blog about our current Kx and Thomson Reuters partnership. Over the past 12 months Kx and Thomson Reuters’ domain experts, and engineers have jumped into the Velocity Analytics 8 product development process with good faith and real enthusiasm. Out of that has come a product delivery, roadmap and sales strategy that both companies are proud of. To both firms credit, we seem to have avoided the dreaded “not-invented-here” syndrome. Both companies have brought the best of their technologies together to create a product which builds on, and exceeds, the foundation on which it is built.
