It's time for the cherry on top - Workflow component. Orchestration vs. choreography it's a never-ending debate :).
The final part of our Saga patterns in #Kalix blog series by @aludwikowski can be found below. The first four parts of this series examined choreography-based Sagas, and this last one will cover the second Saga flavor - orchestration. #Lightbend.

Have a look at what you should expect when implementing DLQ for an ordered stream of events. Tricky stuff.
Check out part 4 of our Saga patterns in #Kalix blog series written by @aludwikowski. This blog talks about error handling, one of the most tricky parts when working with long-lived business processes. #Lightbend #SagaPattern #Microservices #Developer.

I hate performance testing and love it at the same time. Check out the results, but don't get used to them too much, the next article is coming. Event sourcing in #Java with #Akka and #PostgreSQL.

The first episode of a new series focused on benchmarking Event Sourcing solutions where we implement an Event Sourcing solution based on the Akka stack in Java.
