Generating a Zeebe-Python Client Stub in Less Than An Hour: A gRPC + Zeebe Tutorial
Please note that this blog post has not been updated since its original publication to reflect changes to Zeebe’s gateway.proto file.
The general approach for creating a stub that we show here still applies to newer versions of Zeebe, but you may need to make a few modifications depending on which Zeebe version you’re using.
The high points:
- Starting in Zeebe 0.12, Zeebe clients communicate with brokers via a stateless gRPC gateway, with Protocol Buffers used as the interface design language and message interchange format.
- gRPC makes it easy to generate a “client stub” in any of ten supported programming languages; this means it’s possible to use Zeebe in applications written in not only Java and Go–the languages with officially-supported Zeebe clients–but also Python, Ruby, C#, PHP, and more.
- We’ll show you step-by-step how we generated and started prototyping with a Python client stub in less than an hour, and we’ll provide everything you need to follow along.

Event-Driven Orchestration: Message Events and Message Correlation in ZeebeZeebe 0.12 supports message events, making it easy to use Zeebe as part of an event-driven architecture; workflow instances can to respond to events published by external systems. And Zeebe handles all of the heavy lifting related to correlating a message to a workflow instance: buffering incoming messages, opening a subscription to receive messages that match with active workflow instances, and correlating a message (when one exists) to a workflow instance that has arrived at a message event.

Announcing the Zeebe 0.12 Release: Message Correlation, Parallel Processing, and More
The Zeebe team is excited to announce the 0.12 release. To get started with Zeebe 0.12, please see our installation guide.
It’s been 3 months since the Zeebe 0.11 release, and we’ve been hard at work adding new BPMN symbols that will enable Zeebe to support a range of new use cases.
The 0.12 release also includes a number of architectural changes to Zeebe that make it a much simpler system that’s more focused on its core use case: high-throughput, low-latency workflow automation.Read more…

Stateful Orchestration (or, Why Your Microservices Application Needs a Brain)
When checking in for a flight online, normal people hope that everything works the way it’s supposed to. That usually means no error messages, and at the end of the process, getting a boarding pass in your selected format.
We at Camunda, however, are not “normal people”.
A problem during check-in is a bit of a thrill for us because it gives us a peek into how a company handles software failures in a high-traffic application.
We never know exactly what’s happening under the hood, of course, but we like to speculate.Read more…
