Confluent Developer ft. Tim Berglund, Adi Polak & Viktor Gamov

Lena Hall joins Tim Berglund in the studio to talk about Apache Kafka®, the various ways to run Kafka on Microsoft Azure, Kafka on Kubernetes (K8s), and some exciting events that are happening in the Kafka world. 

Lena shares about serving double duty as both a senior software engineer and senior cloud developer advocate for Azure Engineering, including her unique roles and responsibilities, and how she balances engineering with advocacy. From writing tech articles to her experience with fuzzing and presence on YouTube, Lena is a strong community supporter and believes in the importance of staying rooted in the world of code as an advocate, because it helps you better understand common challenges and gives you insight as an engineer trying to fix them. It’s important to ask what's good about it and how it can be improved.

They also discuss Kubernetes, the benefits of running Kafka on Kubernetes, why it’s popular, and using systems that can integrate with it. With Confluent Operator, it’s faster to spin up new environments, as well as easier to support a larger number of clusters in addition to scaling and configuration changes. As the Kafka ecosystem continues to grow and progress, one of the most notable updates of all is KIP-500 involving ZooKeeper.

Helping users be successful when it comes to using Apache Kafka® is a large part of Dani Traphagen’s role as a senior systems engineer at Confluent. Whether she’s advising companies on implementing parts of Kafka or rebuilding their systems entirely from the ground up, Dani is passionate about event-driven architecture and the way streaming data provides real-time insights on business activity. 

She explains the concept of a stream, topic, key, and stream-table duality, and how each of these pieces relate to one another. When it comes to data modeling, Dani covers importance business requirements, including the need for a domain model, practicing domain-driven design principles, and bounded context. She also discusses the attributes of data modeling: time, source, key, header, metadata, and payload, in addition to exploring the significance of data governance and lineage and performing joins.

Tim Berglund sits down with Colin McCabe and Jason Gustafson to talk about KIP-500. The pair, who work on the Kafka Core Engineering Team, discuss the history of Kafka, the creation of KIP-500, and what it will do for the community as a whole. They break down ZooKeeper's role in Kafka, the implications of removing ZooKeeper dependency, replacing it with a self-managed metadata quorum, and how they've been combatting security, stability, and compatibility issues. With pending improvements towards scalability and inter-broker communication, and now that KIP-500 has been adopted within the community—there's a lot covered in this episode that you won't want to miss!

When it comes to deploying applications at scale without needing to integrate different pieces of infrastructure yourself, the answer nowadays is increasingly Kubernetes. Kubernetes provides all the building blocks that are needed, and a lot of thought is required to truly create an enterprise-grade Apache Kafka® platform that can be used in production. But before running Kafka on Kubernetes, there are some factors to consider. What are the maturing stages of Kubernetes adoption? How did Datadog experience these stages? Balthazar Rouberol shares what to think about before hopping on Kubernetes hype train.

As Confluent turns five years old, special guest Jay Kreps (Co-founder and CEO, Confluent) brings us back to his early development days of coding Apache Kafka® over a Christmas holiday while working at LinkedIn. Kafka has become a breakthrough open source distributed streaming platform based on an abstraction of the distributed commit log, and his involvement in the project eventually led him to start Confluent with Jun Rao and Neha Narkhede. 

In this episode, Jay shares about all the highs and lows along the way, including some of his favorite customer success stories with companies like Lyft and Euronext, which empower their real-time businesses through event streaming with Confluent Cloud.

Starting a company certainly comes with more than the technology, and Jay also reflects on some of the challenges around funding, support, and introducing Confluent to the rest of the world. How they have brought us from the beginning to now yields some wise words from Jay to any developer who is interested in establishing their own startup.

What’s a graph? How does Cypher work? In today's episode of Streaming Audio, Tim Berglund sits down with Michael Hunger (Lead of Neo4j Labs) and David Allen (Partner Solution Architect, Neo4j) to discuss Neo4j basics and get the scoop on major features introduced in Neo4j 3.4 and 3.5. Among these are geospatial and temporal types, but there’s also more to come in 4.0: a multi-database feature, fine-grained security, and reactive drivers/Spring Data Neo4j RX. 

In addition to sharing a little bit about the history of the integration and features in relation to Apache Kafka®, they also discuss change data capture (CDC), using Neo4j to put graph operations into an event streaming application, and how GraphQL fits in with event streaming and GRANDstack. The goal is to add graph abilities to help any distributed application become more successful.
