Don't let this gap widen
Without mastery of Kafka Clients, beginner developers deploy unreliable producers and consumers, leading to data corruption and message loss in real-time streams.
Industry reports indicate 62% of production Kafka outages trace back to client-side errors, averaging $180,000 in downtime costs per incident for mid-sized firms.
These failures cascade into stalled operations, regulatory fines, and eroded stakeholder trust, jeopardizing team deliverables and individual career trajectories.
Every quarter without solid Kafka Client skills, companies forfeit 25% in processing efficiency, amplifying risks in scalable data architectures.
The Kafka Clients Initiation Training training is delivered in-person or remotely (blended-learning, e-learning, virtual classroom, remote in-person). At Learni, a Qualiopi-certified training organization, each program is designed to maximize skills acquisition, regardless of the training mode chosen.
The trainer alternates between demonstrative, interrogative, and active methods (through practical exercises and/or real-world scenarios). This pedagogical approach ensures concrete and directly applicable learning in the workplace.
To ensure the quality of the Kafka Clients Initiation Training training, Learni provides the following teaching resources:
For in-house training at a location external to Learni, the client ensures and commits to having all necessary teaching materials (IT equipment, internet connection...) for the proper conduct of the training action in accordance with the prerequisites indicated in the communicated training program.

Discover Apache Kafka, a powerful streaming tool for managing massive data streams. Install Kafka locally, configure a simple cluster, and create your first topics. Explore Kafka architecture including brokers, partitions, and replication. Master key concepts: Producers send messages, Consumers read messages, Consumer groups, and offset management. Launch Kafka with Docker, test your setup, write your first script, check logs, and resolve common errors. Content optimized for beginners with practical training from the start to help you become autonomous quickly, integrate Kafka into your projects, learn best practices, and avoid common pitfalls. Interactive sessions with live Q&A and personalized support. 7 intense hours today.
Dive into Kafka Producers, essential producer clients. Use the Java Kafka API, add the Maven dependency, create a Producer class, and configure key properties: bootstrap servers, key serializer, value serializer. Send synchronous and asynchronous messages with callbacks for feedback. Handle send errors with automatic retries and appropriate timeouts. Produce in batches to improve performance. Test with console producer, integrate with a Spring Boot app, serialize JSON data, and use basic Avro schemas. Monitor Producer metrics and detailed logs for easy debugging. Multiple practical exercises: code live and apply at home. Master Producers in one day and apply immediately to real simulated projects. 7 hands-on hours.
Explore Kafka Consumers for reliable message reading. Detailed Java Consumer API: required properties like unique Group ID, auto offset commit, secure manual commits, efficient poll loops, heartbeat intervals, and session timeouts. Handle partition rebalancing with assign vs. subscribe. Consume from a single topic or multiple topics, filter by key, deserialize payloads, and process messages in batches. Introduction to exactly-once semantics and transactions. Test with console consumer, integrate with Spring Kafka, robust error handling, basic Dead Letter Queue. Optimize Consumer metrics and performance. Guided exercises: code your first consumer and debug in groups. Perfect initiation to become a Kafka Clients pro. 7 immersive hours.
Apply everything in a final project combining Producer and Consumer in a complete Kafka app with end-to-end data flows. Integrate with databases: MySQL to Kafka and Kafka to Elasticsearch. Complementary tools: Kafka UI for monitoring, introduction to Confluent Schema Registry. Basic security with SASL and HTTPS setup. Best practices for scalability, multi-node clustering, high availability, common troubleshooting, avoiding OOM Killer, and efficient partitioning. Challenging exercises, present your project, receive expert feedback, review QCM, and receive initiation certificate. Access to video replays and post-training support. Networking with participants. Total 28 intense hours.
