[Blog post for developers] Using Delayed Delivery Queues in Your Event Mesh to Implement Timers
When building an application using a microservices architecture, it is much easier to horizontally scale those microservices – i.e, adding more service instances on demand – when those microservices are stateless. However, implementing timers can be a challenge. How can you “set aside” an event to be processed later, perhaps by a different instance of the microservice, without storing processing state in the microservice? The answer is to use a delayed delivery queue in your event mesh.
In this blog post, Steve Buchko, Solace’s VP of Product Management, Core Products, explores two scenarios in an e-commerce application example where delayed delivery queues really come in handy:
- Retrying processing after a time delay. I’ll use a credit card purchase authorization in an e-commerce application to illustrate this use case.
- One event, published to the event mesh, processed by different microservices at different times
