In a microservices environment, classic ACID transactions across multiple services are not feasible.
Each service typically owns its own database, making distributed transactions complex, slow, and fragile.
Transaction handling is straightforward in monolithic applications.
A single database, a single transaction boundary, and frameworks like Spring make it almost effortless with the @Transactional annotation.
In the previous article, we explored why transaction management becomes problematic in microservices — especially when services are poorly split and rely on synchronous REST calls.
Now let’s look at how transactions can be handled correctly in a Spring Boot-based microservice architecture.
