The Harsh Reality of Building a Realtime ML Feature Platform

In a world where AI and ML are rapidly evolving, the need for efficient Realtime Feature Platforms has never been greater. But the journey to create one is far from straightforward.

In the talk, Ivan Burmistrov will share how ShareChat - the largest social network in India - built their own Realtime Feature Platform serving more than 1 billion features per second, and how they managed to make it cost-efficient.

Ivan will cover the challenges the team faced along the way, how they managed to overcome them and which ones are still not fully resolved. The talk will also cover the experience in using relatively new technologies such as ScyllaDB and RedPanda and why such technologies are crucial for building a cost efficient system. Additionally, Ivan will share how the system leverages Apache Flink in the very core of the data pipeline.

This talk will provide insights for anyone interested in real-time data pipelines and Realtime Feature Platforms, in particular. 

What's the focus of your work these days?

I'm a Principal Software Engineer at ShareChat, working on infrastructure for a recommendation system, with a particular focus on a realtime feature store and other data-related systems.

What's the motivation for your talk at QCon London 2024?

Building a realtime feature store has been a lot of fun, and there are a lot of real-life lessons I've learned -  which are hard to find online. So, the motivation is to share something worthwhile.

How would you describe your main persona and target audience for this session?

Anyone who is curious about realtime data processing and low-latency systems.

Is there anything specific that you'd like people to walk away with after watching your session?

I'd like attendees to walk away with an understanding of what it takes to build a realtime feature store, and generic tips and tricks on realtime data processing.
