Stream processing of real-time data enables business leaders to discover new insights that can’t be gleaned from reports after the fact. Those companies that can act on these insights in real-time can innovate and disrupt established business sectors.

The most significant and profitable insights need immediate action. Hence, streaming analytics are fuelling business innovation and it is becoming essential that organisations can react in real-time to the information they are collecting and processing as part of their business functions.

Kx technology directly addresses the requirements of streaming analytics. There are three key technology approaches that are driving the need for a solution:

  1. The arrival of new data architectures, as seen within the Big Data arena, now looking for a streaming architecture.
  1. The Internet of Things (IoT): assets, sensors, machines pushing data into real-time analytics and operational management.
  1. Cloud analytics: cloud deployments are increasingly looking at dealing with real-time ingestion and distribution.

How does streaming processing change things? The most common type of analytic processing is based on a pull model: the data is collected in a repository and queries are run against the data. The responses are based on the data at the query time. Queries have to be rerun as the data updates, and results may take seconds, minutes or even hours to produce. This is a reactive style of management; the insight in the data is only realised when someone looks for that value.

The new paradigm is to have “active queries” where the answers update in real-time as the data changes. This is streaming analytics.

One of the key drivers, IoT, embodies these concepts. IoT is connecting objects and devices: everything from cell phones, televisions, fitness trackers, as well as manufacturing equipment, automobiles and jet engines. IoT is creating real-time business events that present significant opportunities for companies to transform how they: engage with customers, operate their business and deliver their services. However, in order to do this, companies are faced with the task of analysing large volumes of data; in motion and at rest. Their challenge is to identify patterns, assess the past, make real-time predictions and act on these insights.

After quietly dominating the real-time decision processing space in finance for years, Kx looked at other industries and realised it already had the technologies they were trying to build and integrate. Their projects to capture and process business events, were requiring them to become software developers and system integrators, distracting them from their main purpose: to serve their customers with better products and value.

We believe that Gartner, in their white paper ‘How to Select In-Memory Computing Technologies for Big Data*’, have managed to distill the components required to implement a state of the art platform for making real-time insights into business events. Gartner have clearly defined the components required and how they need to interoperate. We believe the task of integrating several open source packages for this architecture may not be the most performant solution nor the most cost effective.

 

Kx offers an alternative approach: one that is complete, supported and proven in the harshest of real-time environments, financial services.

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.
