Event-Driven Apps

Streaming, event processing and batch processing are popular technologies and often misused as a better "RPC".

In this workshop we will focus on killer use cases, as well as planning, architecting and designing streaming, messaging, batch / microbatch systems.

Prerequisites

Java EE / Jakarta EE / MicroProfile knowledge (I will use Java EE concepts to explain streaming and messaging).

Topics

• What is "event-driven"?
• Messages vs. Events / JMS vs. Kafka
• Reactive programming with event streams and "traditional" MicroProfile APIs
• Why streaming will significantly impact your architecture
• Events, transactions and consistency
• Dealing with XA / 2PC
• Streams vs. Tables
• Thinking in events
• MicroProfile Reactive Stream Operators
• MicroProfile Reactive Messaging
• CQRS architectures
• Apache Kafka with / vs. MicroServices
• Java 8+ streams vs. streaming
• From batches, microbatches to streaming
• Event stream processing and integrations
• Possible Machine Learning integrations
• Kafka Consumers / Producers, Streams and KSQL
• Apache Kafka, Apache Pulsar and Co.
• Apache Kafka scalability, consistency and load balancing
• Under the hood of Apache Kafka
• Kafka load balancing, HA and MicroProfile / Jakarta EE integration
• Relational DBs and NoSQL vs. persistent event logs
• Change Data Capture (CDC)
• Debezium and DB integration
• Reactive programming and JAX-RS, Kafka, SSE integrations
• Reactive Programming with SmallRye Mutiny
• Scalability and consistency challenges
• Clustering and replication techniques
• Integration with traditional application servers and MicroProfile runtimes
• Topics, Queues, Consistency, Transactions and Persistence
• ...and most popular questions, topics and technologies from airhacks.tv

In this advanced workshop I would like to explain the most significant features with working code and prepared examples. As a reference, you will get a GIT repository with all snippets and solutions, as well as prepared sample applications.

A developer laptop with pre-installed Java 11(+), GIT-client and Maven 3 is required to run the examples. You can run the examples if you like, or "hack" along with me, but taking notes is perfectly viable as well.

Environment requirements / prerequisites.

I/we will spend 90% of the time in code.
