Building High-Throughput, Low-Latency Pipelines in Kafkaconfluent
William Hill is one of the UK’s largest, most well-established gaming companies with a global presence across 9 countries with over 16,000 employees. In recent years the gaming industry and in particular sports betting, has been revolutionised by technology. Customers now demand a wide range of events and markets to bet on both pre-game and in-play 24/7. This has driven out a business need to process more data, provide more updates and offer more markets and prices in real time.
At William Hill, we have invested in a completely new trading platform using Apache Kafka. We process vast quantities of data from a variety of feeds, this data is fed through a variety of odds compilation models, before being piped out to UI apps for use by our trading teams to provide events, markets and pricing data out to various end points across the whole of William Hill. We deal with thousands of sporting events, each with sometimes hundreds of betting markets, each market receiving hundreds of updates. This scales up to vast numbers of messages flowing through our system. We have to process, transform and route that data in real time. Using Apache Kafka, we have built a high throughput, low latency pipeline, based on Cloud hosted Microservices. When we started, we were on a steep learning curve with Kafka, Microservices and associated technologies. This led to fast learnings and fast failings.
In this session, we will tell the story of what we built, what went well, what didn’t go so well and what we learnt. This is a story of how a team of developers learnt (and are still learning) how to use Kafka. We hope that you will be able to take away lessons and learnings of how to build a data processing pipeline with Apache Kafka.
Kafka, Apache Kafka evolved from an enterprise messaging system to a fully distributed streaming data platform (Kafka Core + Kafka Connect + Kafka Streams) for building streaming data pipelines and streaming data applications.
This talk, that I gave at the Chicago Java Users Group (CJUG) on June 8th 2017, is mainly focusing on Kafka Streams, a lightweight open source Java library for building stream processing applications on top of Kafka using Kafka topics as input/output.
You will learn more about the following:
1. Apache Kafka: a Streaming Data Platform
2. Overview of Kafka Streams: Before Kafka Streams? What is Kafka Streams? Why Kafka Streams? What are Kafka Streams key concepts? Kafka Streams APIs and code examples?
3. Writing, deploying and running your first Kafka Streams application
4. Code and Demo of an end-to-end Kafka-based Streaming Data Application
5. Where to go from here?
Modern businesses have data at their core, and this data is changing continuously. How can we harness this torrent of information in real-time? The answer is stream processing, and the technology that has since become the core platform for streaming data is Apache Kafka. Among the thousands of companies that use Kafka to transform and reshape their industries are the likes of Netflix, Uber, PayPal, and AirBnB, but also established players such as Goldman Sachs, Cisco, and Oracle.
Unfortunately, today’s common architectures for real-time data processing at scale suffer from complexity: there are many technologies that need to be stitched and operated together, and each individual technology is often complex by itself. This has led to a strong discrepancy between how we, as engineers, would like to work vs. how we actually end up working in practice.
In this session we talk about how Apache Kafka helps you to radically simplify your data processing architectures. We cover how you can now build normal applications to serve your real-time processing needs — rather than building clusters or similar special-purpose infrastructure — and still benefit from properties such as high scalability, distributed computing, and fault-tolerance, which are typically associated exclusively with cluster technologies. Notably, we introduce Kafka’s Streams API, its abstractions for streams and tables, and its recently introduced Interactive Queries functionality. As we will see, Kafka makes such architectures equally viable for small, medium, and large scale use cases.

Building Event-Driven Systems with Apache KafkaBrian Ritchie
Event-driven systems provide simplified integration, easy notifications, inherent scalability and improved fault tolerance. In this session we'll cover the basics of building event driven systems and then dive into utilizing Apache Kafka for the infrastructure. Kafka is a fast, scalable, fault-taulerant publish/subscribe messaging system developed by LinkedIn. We will cover the architecture of Kafka and demonstrate code that utilizes this infrastructure including C#, Spark, ELK and more.
Sample code: https://github.com/dotnetpowered/StreamProcessingSample
Real time Messages at Scale with Apache Kafka and CouchbaseWill Gardella
Kafka is a scalable, distributed publish subscribe messaging system that's used as a data transmission backbone in many data intensive digital businesses. Couchbase Server is a scalable, flexible document database that's fast, agile, and elastic. Because they both appeal to the same type of customers, Couchbase and Kafka are often used together.
This presentation from a meetup in Mountain View describes Kafka's design and why people use it, Couchbase Server and its uses, and the use cases for both together. Also covered is a description and demo of Couchbase Server writing documents to a Kafka topic and consuming messages from a Kafka topic. using the Couchbase Kafka Connector.
Monitoring and Resiliency Testing our Apache Kafka Clusters at Goldman Sachs ...HostedbyConfluent
In our payments platform at Goldman Sachs Transaction Banking, Apache Kafka plays a critical role as the messaging bus in our micro-services architecture. Being a part of the financial service industry we need to ensure high-availability of our platform and quick response time during failures.
In this talk we will explore how we monitor and alert on the health of our Kafka clusters using our heartbeat application and clients using DataDog dashboards. We will see how we consolidate JMX metrics such as error-rates, connection-rates, latencies and consumer lag from all producers and consumers using JMX agent sidecar to provide a live view of the health of our entire infrastructure. We will also discuss our culture of game days where we regularly test the resiliency of all the clients in our infrastructure by simulating various failure scenarios to improve the overall availability of our infrastructure.
Everything you ever needed to know about Kafka on Kubernetes but were afraid ...HostedbyConfluent
Kubernetes became the de-facto standard for running cloud-native applications. And many users turn to it also to run stateful applications such as Apache Kafka. You can use different tools to deploy Kafka on Kubernetes - write your own YAML files, use Helm Charts, or go for one of the available operators. But there is one thing all of these have in common. You still need very good knowledge of Kubernetes to make sure your Kafka cluster works properly in all situations. This talk will cover different Kubernetes features such as resources, affinity, tolerations, pod disruption budgets, topology spread constraints and more. And it will explain why they are important for Apache Kafka and how to use them. If you are interested in running Kafka on Kubernetes and do not know all of these, this is a talk for you.
Uber has one of the largest Kafka deployment in the industry. To improve the scalability and availability, we developed and deployed a novel federated Kafka cluster setup which hides the cluster details from producers/consumers. Users do not need to know which cluster a topic resides and the clients view a "logical cluster". The federation layer will map the clients to the actual physical clusters, and keep the location of the physical cluster transparent from the user. Cluster federation brings us several benefits to support our business growth and ease our daily operation. In particular, Client control. Inside Uber there are a large of applications and clients on Kafka, and it's challenging to migrate a topic with live consumers between clusters. Coordinations with the users are usually needed to shift their traffic to the migrated cluster. Cluster federation enables much control of the clients from the server side by enabling consumer traffic redirection to another physical cluster without restarting the application. Scalability: With federation, the Kafka service can horizontally scale by adding more clusters when a cluster is full. The topics can freely migrate to a new cluster without notifying the users or restarting the clients. Moreover, no matter how many physical clusters we manage per topic type, from the user perspective, they view only one logical cluster. Availability: With a topic replicated to at least two clusters we can tolerate a single cluster failure by redirecting the clients to the secondary cluster without performing a region-failover. This also provides much freedom and alleviates the risks for us to carry out important maintenance on a critical cluster. Before the maintenance, we mark the cluster as a secondary and migrate off the live traffic and consumers. We will present the details of the architecture and several interesting technical challenges we overcame.
A Modern C++ Kafka API | Kenneth Jia, Morgan StanleyHostedbyConfluent
We wanted to embed a Kafka producer/consumer in C++ and decided to use ""librdkafka"", a robust C/C++ library that is open source, well-maintained, and widely used.
The C++ interface of ""librdkafka"" is confined to C++ 98 for compatibility, which makes it less object-oriented and user-friendly. Raw pointers in the interface complicates object lifecycle management and limited encapsulation leading to a more complex API.
That is why we built a C++ Kafka API using modern C++ as a wrapper on top of ""librdkafka"". This header-only library is quite similar to the Java API, object-oriented and user-friendly. It frees us from the burdens mentioned above so even a novice can pick it up and work out an efficient solution.
The ""modern-cpp-kafka"" project on github has been thoroughly tested within our company. After using it to replace a legacy implementation, throughput for a key middleware system gained 26%!
Welcome to Kafka; We’re Glad You’re Here (Dave Klein, Centene) Kafka Summit 2020confluent
Apache Kafka sits at the center of a technology ecosystem that can be a bit overwhelming to someone just getting started. Fortunately, Apache Kafka is also at the heart of an amazing community that is able and eager to help! So, if you are new, or relatively new, to Apache Kafka, welcome! I’d like to introduce you to the Kafka ecosystem, and present you with a plan for how to learn and be productive with it. I’d also like to introduce you to one of the most helpful and welcoming software communities I’ve ever encountered.
I’ll take you through the basics of Kafka—the brokers, the partitions, the topics—and then on and up into the different APIs and tools that are available to work with it. Consider it a Kafka 101, if you will. We’ll stay at a high level, but we’ll cover a lot of ground, with an emphasis on where and how you can dig in deeper.
I am still learning myself, so I will share with you what and who have helped me in my journey, and then I’ll invite you to continue that journey with me. It’s going to be a great adventure!
Reducing Microservice Complexity with Kafka and Reactive Streamsjimriecken
My talk from ScalaDays 2016 in New York on May 11, 2016:
Transitioning from a monolithic application to a set of microservices can help increase performance and scalability, but it can also drastically increase complexity. Layers of inter-service network calls for add latency and an increasing risk of failure where previously only local function calls existed. In this talk, I'll speak about how to tame this complexity using Apache Kafka and Reactive Streams to:
- Extract non-critical processing from the critical path of your application to reduce request latency
- Provide back-pressure to handle both slow and fast producers/consumers
- Maintain high availability, high performance, and reliable messaging
- Evolve message payloads while maintaining backwards and forwards compatibility.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
