A summary of my recent #Akka benchmarking activity, up to 1,000,000 req/s. Mixed load: 75% reads, 25% (consistent) writes. All done with moderate Postgres DBs. lightbend.com/blog/benchmark…

What is your most wanted #java21 feature 🤔
#UncoverJava with us and check what @jMargaritaN @aludwikowski @piotrprz @NoobFunctor can't wait for!

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.

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.

3/5 - the most generic part. Having a rich deduplication strategies toolbox is the key for distributed system development.

1/5. Four more to come. No more trivial examples, the code will get more and more interesting :)

Happy to share, that I've been working on this new #Kalix feature for the past few months. It's ready to use, but we're planning to make it even more powerful. More detailed Saga pattern blog post series coming soon kalix.io/developer/blog/intr…

#ICYMI #JMeter & #Gatling are one of the most popular performance testing tools. @aludwikowski has been using both for quite some time and he has summarized his experiences in this #InfoQ article: bit.ly/3PeZdsq

Did you know that you can manage at-least-once delivery not only on the producer but also on the consumer side? 💡

We can now use #Gatling with the #Java language! On our blog, @aludwikowski tries it out on a sample scenario to verify the new performance-test-as-a-code Java DSL:

In the 2nd part of the Reactive Event Sourcing Benchmarks series, @aludwikowski continues the exploration of #PostgreSQL, this time focusing on more pessimistic load generation.

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. softwaremill.com/reactive-ev… Event sourcing in #Java with #Akka and #PostgreSQL
What a nice surprise after the holidays. Finally, my article about #Gatling and #JMeter was published on @InfoQ
#JMeter & #Gatling are one of the most popular performance #TestingTools.

Looking for some cool, developed by proven @apachekafka experts #educational tool? 🧑💻
Try Kafka #Visualization, where you can simulate how #data flows through a replicated Kafka topic, to gain a better understanding of the message processing model. 👇
