Disasters are inevitable; hardware failure, network problems and data corruption are all events which could play havoc with a system. If these events are not fully understood and planned for they may lead to significant downtime and potentially severe business impact, including revenue loss, legal and financial implications, and impact to business reputation and brand. Recent high-profile systems failures of a large cloud computing provider and an international airline highlight the importance for IT systems to have a comprehensive disaster recovery plan in place.

This whitepaper discusses disaster recovery (DR) and failover concepts from the perspective of the gateway layer accessing a typical kdb+ tick system used in capital markets applications. The end goal of constructing this plan is to ensure high availability of the application via the gateway where possible, considering all conceivable failure scenarios and outlining any actions required to prevent data loss, minimize any downtime and keep the application accessible.

Kdb+ Use Case: Machine Learning Water System Maintenance Application

6 Dec 2017 | , , , ,

Kdb+ is being used much more widely in machine learning applications today. Its ability to quickly ingest and process data, particularly large, fragmented datasets, is one way that developers are adding kdb+ to their technology stack of artificial intelligence and machine learning tools.
For Australian kdb+ developer Sherief Khorshid, who also develops machine learning systems, incorporating kdb+ into a predictive maintenance application gave him the edge in a hackathon win that landed him a cash prize and a contract with the Water Corporation of Western Australia.

Kdb+ FFI: Access external libraries more easily from q

22 Nov 2017 | , , ,

Following on from the hugely popular Python library and interface embedPy and PyQ, Kx has released an FFI as part of the Fusion for kdb+ interfaces. As with embedPy and PyQ, this FFI is open-sourced under the Apache 2 license.
The kdb+ FFI is a foreign function interface library for loading and calling dynamic libraries from q code. It has been adapted and expanded upon from a library originally written by Alex Belopolsky of Enlightenment Research. With the kdb+ FFI you can now call your favorite C/C++ libraries directly from q without the overhead of having to compile shared objects and load into q using the 2: command.
