Laying the Foundations for a Kappa Architecture - The Yellow Brick Road

In the ever changing landscape of big data, focus is slowly moving away from batch and towards realtime analytics. Data Science workflows are evolving to adapt to this changing landscape. Realtime analytics are limited only by the underlying architecture that enables low latency ingestion, processing and serving of high throughput data. Lambda architecture unified batch and realtime to provide low latency computations with eventual correctness. However the challenges of maintaining two different codebases(among other things) made operations hard.

The founder of Kafka talks about a streaming first kappa architecture in this 2014 article. A streaming first, single path solution that can handle realtime processing as well as reprocessing and backfills. Kappa architecture makes sense, however it is 2023 and it has a long way to go for full scale adoption. A paradigm shift is required in how we design data infrastructure. Now, instead of worrying about two codebases, we need to worry about bootstrapping from a stream, backfills from history, idempotent sinks to handle reprocessing etc.

In this presentation, I will talk about strategies to evolve your Data Infrastructure to enable Kappa architecture in your organization. An iterative roadmap to move away from Lambda, while ensuring minimum disruption to end-users. I will be using real world examples from tech companies as case studies. By the end of this presentation you will walk away with a concrete roadmap for designing a data platform built on Kappa architecture.
