Armeria VS Flowable (V6)

OP doesn't seem to be aware of Armeria https://github.com/line/armeria

Armeria (https://armeria.dev/) is a very underrated framework and does not get enough love, it works fabulously with Kotlin (coroutines support also built-in) and integrates nicely with GRPC, Thrift, etc. The maintainers are very responsive and nice and always helping people out.

Honestly yes? Higher pay, less overtime.

Enjoy https://github.com/line/armeria from a unionized tech company of South Korea!

If you want something really small that simply let's you expose REST APIs using plain Java, without the IoC containers, you might want to check out Javalin, Ratpack or Armeria

Check out Armeria, it's a newer framework from the creator of Netty for micro services and comes with many builtin functionalities for service discovery, logging and fault tolerance. It's getting a lot of adoption from companies like Slack, Doordash, Afterpay and Databricks too. It kind of reminds me of Finagle from the Scala ecosystem in that it supports many different protocols (gRPC, thrift and HTTP).

Armeria which fully supports Reactive Streams and non-blocking IO now powers sttp as a backend.

I’m doing a lot of exploratory work with BPMN right now.

I think if your business is largely transactional (think Stripe), there is a lot of value to be had by framing your development as “business process automation”.

The term (and BPMN) has a lot of enterprise baggage, but some of the tools out there [0][1] are well suited to orchestrating services (and people where necessary) as a single automated process. The the ability to build that flow visually using BPMN, and then execute it in a workflow engine where you can monitor it, audit it, and optimize over time is pretty compelling.

Here’s an interesting read on the topic: https://www.infoq.com/articles/events-workflow-automation/
