Kafka Summit Europe 2021

A talk discussing the rise of Apache Kafka and data in motion plus the impact of cloud native data systems. This talk will cover how Kafka needs to evolve to keep up with the future of cloud, what this means for distributed systems engineers, and what work is being done to truly make Kafka Cloud...

Today’s data is in motion. Enterprises need to see their business and their data in near real time; they need to respond in milliseconds not hours; and they need to integrate, aggregate, curate, and disseminate data within and across production environments.

Organizations have been chasing the dream of data democratization, unlocking and accessing data at scale to serve their customers and business, for over a half a century from early days of data warehousing. They have been trying to reach this dream through multiple generations of architectures...

At Stripe, we operate a general ledger modeled as double-entry bookkeeping for all financial transactions. Warehousing such data is challenging due to its high volume and high cardinality of unique accounts. Apache Pinot works well in synergy with Kafka to provide an excellent solution.

While Kafka has guarantees around the number of server failures a cluster can tolerate, to avoid service interruptions, or even data loss, it is prudent to have infrastructure in place for when an environment becomes unavailable during a planned or unplanned outage.

Event-Driven Architectures (EDA ) are perceived as mythical objects that instantly transform your systems into ""real-time"" ones! BUT, come to think of it, aren't they already ""real-time""? I mean, adding an item to the cart is pretty much instant in ( most ) webshops.

Kafka has become more than a simple message bus: with a full stack of tooling and new concepts, it’s easy to start deploying complex service meshes, communicating through Kafka, enabling decoupled microservices, stable performance, high scalability and reusability.

Event-driven systems come in different shapes and sizes, and the rules for payload construction are: there are no rules (but there are guidelines). Flexible payloads are both the best and worst thing about event streaming - you never quite know what to expect from each system's payloads.

FREE NOW business is growing rapidly as a ride-hailing industry in general which creates a fair amount of technical challenges related to real-time data aggregation and processing.

In this talk I’ll go over how we built an opinionated Kafka client to easily enable Data Scientists to deploy and own production Kafka consumers, by focusing on writing python functions rather than fighting pitfalls with Kafka.

Whilst Kafka has the ability to encrypt data in transit, it does not have the functionality out of the box to encrypt data at rest. This places the responsibility of encryption of data placed on message queues on developers. Implementing cryptography correctly in our applications is challenging ...

Handling failures is important, but it’s a must have when a product handles sensitive data. It also becomes exponentially harder in the world of microservices, since a failure can happen in any of the services and even in their dependencies.

Legacy systems are the kings of our IT architecture. They rule the evolution of the technology ecosystem that hosts them thanks to the control they have acquired over time on core data and key business processes.
