Écrit par

Spring has arrived in the northern hemisphere, and as we delight in the sight of flowers blossoming, trees budding, and greenery sprouting, we're reminded of the promise of brighter and warmer days ahead. It's time to dust off our bikes, try out new hobbies, and, of course, keep up with the latest trends in data streaming. For those of us in the tech industry, there's always something new to learn and exciting data streaming trends to explore. To help you stay up to date, we're excited to present a roundup of data streaming learning resources for the 2023 spring edition. Count on coming away with a deeper understanding of the data streaming ecosystem, including:

  • Fundamental concepts of Apache Kafka, ksqlDB, and streaming pipelines

  • Developing trends in streaming architecture (Hello, data mesh!)

  • How managed services are taking data streaming to a whole new level

  • Real-life data streaming use cases that are fueling impressive outcomes

  • How you can connect with a community of data streaming experts and enthusiasts

Looking to understand the basics of data streaming and how it can transform your business? Check out our Data Streaming Resources Hub to get up to speed with some of the latest explainer videos, case studies, and industry reports!

Ready for a deeper dive? We’ve got you covered. Here’s a roundup of some of the best resources for learning about data streaming:

What data streaming does and why it’s important

When you’re getting started with data streaming concepts, get to know Apache Kafka first with Intro to Apache Kafka: How Kafka Works. Kafka is the foundational open-source technology behind data streaming (including Confluent Cloud’s managed service), and in this blog post you’ll find the basics of how Apache Kafka operates and an introduction to its primary concepts, including events, topics, partitions, producers and consumers, and more.

Next, check out Top 5 Things Every Apache Kafka Developer Should Know to get a sense of how to achieve better Kafka performance and get more details on the architectural concepts. From there, brush up on data system design with Introduction to Streaming Data Pipelines with Apache Kafka and ksqlDB. A data pipeline moves data from one system to another, and streaming pipelines put event streaming into action to bring accurate, relevant data to teams across a business while avoiding batch processing bottlenecks. Confluent’s ksqlDB acts as the processing layer for streaming pipelines and lets you perform operations on data before it goes to its targets.

Where data streaming fits into the bigger picture

Once you’ve got the basics down and a mental map of how Kafka works, see how it fits into the larger modern data industry and into your data architecture in particular. Kafka is part of the trend toward decentralized architectures that can enable better productivity and overall performance as teams and systems can work independently. In An Introduction to Data Mesh, take a look at the concept of a central nervous system driven by data streaming, also known as a data mesh. This approach to data and organizational management is centered around decentralization of data ownership, and involves four principles: data ownership by domain, data as a product, self-service data platform, and federated governance.

When and how a managed service comes into the picture

There are plenty of ways to get started using Apache Kafka across your organization. Once data streaming reaches mission-critical status, though, a managed service like Confluent Cloud can speed up deployment with features like fully managed connectors, infinite storage, and lots more. See the fundamentals of a managed data streaming service in A Walk to the Cloud, illustrated by friendly otters and a clouded leopard who take the leap from the wild Kafka river to the cloud.

Using data streaming in real life

The use cases for event streaming or data streaming are nearly endless for modern businesses, all trying to stay ahead of the competition by anticipating what’s next and doing it cost-efficiently. Check out this Data Streaming 101 infographic to see how one retailer incorporated managed event streaming services so that inventory levels and customer orders stay in sync, and both back-end and front-end systems perform at their best.

Finding your fellow data streaming students

To start putting your knowledge into practice with some test cases, join the data streaming social media community in Succeeding at 100 Days Of Code for Apache Kafka. This project challenges you to take part in your own hands-on learning journey for at least an hour a day for 100 days. Stay connected with your fellow coders on Twitter, LinkedIn, or other preferred channels along the way to share your progress with #100DaysofCode and @apachekafka.

Start the 100 Days challenge at Confluent Developer to build your own self-directed Kafka learning path, and bring in other new resources as you go—whether getting to know microservices, event sourcing, or GraphQL databases or trying programming languages like Python, Go, or .NET.
