Event-driven Java with Spring Cloud Stream and Azure Event Hubs [Guest Post]

Asir Selvasingh | Principal PM Architect | Microsoft – Java on Azure

Spring Cloud Stream Binder for Azure Event Hubs is now generally available.

It is simple to build highly scalable event-driven Java apps using Spring Cloud Stream with Event Hubs, a fully managed, real-time data ingestion service on Azure that is resilient and reliable service for any situation; this includes emergencies, thanks to its geo-disaster recovery and geo-replication features.

Spring Cloud Stream provides a binder abstraction for popular message broker implementations. It provides a flexible programming model built on already established and familiar Spring idioms and best practices, including support for persistent pub/sub semantics, consumer groups, and stateful partitions. Now, developers can use the same patterns for building Java apps with Event Hubs.

Reactor Debugging Experience

In the Project Reactor team, we believe that the debugging experience of the libraries you rely upon is as important as, let’s say, the feature set or performance.

Today, we’re excited to announce two new experimental projects in the Reactor family!

BlockHound - a new kid on the block

One of the most common rookie mistakes is to block Java threads that are supposed to run only non-blocking code (e.g., Schedulers.parallel()).
It is one of the most harmful issues because you may block unrelated processing or even create a deadlock!
