Productionize Big Data Analytics with Dash & Vaex

Featuring Jovan Veljanoski, Co-Founder of Vaex

Recorded on August 26, 2020

Datasets have become increasingly complex and overwhelming to manage. When faced with Big Data, data scientists turn to Vaex, an open-source DataFrame library in Python specifically designed to work with large datasets using memory mapping. Vaex is the perfect companion to Dash, which uses workers to scale vertically and Kubernetes to scale horizontally. Together, Vaex and Dash empower data scientists to easily create scalable, production-ready web applications. Join Jovan Veljanoski, Co-Founder of, as he demonstrates how to utilize the scalability of Dash and the superb performance of Vaex to implement interactive dashboards displaying a billion records.

During this 1 hour webinar, he'll show you how to:

  • Perform data manipulation, aggregation, and statistic computations for Big Data and Machine Learning using Vaex
  • Capture user interactions and automatically update key components by connecting Vaex to Dash
  • Utilize Dash’s stateless, reactive, functional nature to generate interactive, scalable dashboards
