Description

Introduction

In high-performance environments such as capital markets, telecom, IoT, and real-time monitoring systems, reusable and optimized analytics components are critical for scalability and maintainability. This training focuses on designing and building custom analytics libraries in q within the kdb+ ecosystem.

Participants will learn how to modularize analytics logic, create reusable functions, package libraries, manage dependencies, and deploy enterprise-grade analytics frameworks. The course emphasizes performance optimization, functional programming patterns, and production-ready design practices in q.

By the end of the training, participants will be able to architect scalable analytics toolkits tailored to their organization’s data pipelines and real-time systems.
