Coming in Zeebe 0.21: Long-polling workers
The upcoming 0.21 release of Zeebe includes a feature many users have been asking for: long-polling for workers. And make sure you stay tuned to the end to find out what a massive deal it is. Zeebe is a radical re-imagining of the workflow engine for the modern world: it uses event sourcing to interpret workflows over immutable streams. In the Zeebe model, workers are de-coupled from the broker. Conceptually, workers “subscribe” to task types on the broker to service. Read more…Scaling Zeebe Horizontally: A Simple Benchmark
Zeebe advertises itself as being a “horizontally-scalable workflow engine”. In this post, we cover what that means and how to measure it.
Read more…Zeebe Message Correlation
Message correlation is a powerful feature in Zeebe. It allows you to target a running workflow with a state update from an external system, asynchronously. You can use it to do things like: Update a workflow instance when an item ships from a warehouse, or a customer payment is processed. Cancel a running workflow when a user quits from a game server. Any event in the external world that influences your workflow state. Read more…Announcing the Zeebe and Operate Alpha Releases - August 2019

The latest episode of the Zeebe Nation podcast is out, and it features an interview with Mackenzie Clark, the maintainer of the open source Rust client library for Zeebe - Zeebest. Extract from 00:17:18: Mackenzie: Another reason I liked Zeebe a lot is they were using BPMN - which was (an) ISO standard format - for describing workflows, and I think Conductor was not using BPMN - or they had to have some kind of adapter. Read more…Zeebe Workflows Inside a REST Request/Response
In the Zeebe Slack and the Forum, a number of users have been inquiring about initiating a Zeebe workflow via a REST request, and returning the outcome of the workflow in the REST response. Zeebe workflows are fully decoupled, asynchronous, and have no awaitable outcome. This means there is nothing out-of-the-box right now to do this. We are evaluating demand for this feature in GitHub, both in terms of its eventual shape and its priority. Read more…The Zeebe 0.20.0 (Production Ready) Release Webinar: A Recap

In early July, 2019, I sat down with Daniel Meyer, Camunda CTO and Zeebe Committer #0, to talk about the new Zeebe Community License. This is the transcript of that conversation. Josh Wulf: We have a change to the licensing for Zeebe - probably, people are going to be interested to know more about that. I know you’ve done a lot of work on it - you’ve been speaking with British lawyers most recently about it.

Last Wednesday, July 17, we announced the first production ready release of Zeebe, Camunda’s new cloud-native workflow engine for microservices orchestration. Zeebe is a new code base, written from scratch, putting forward a completely new way of architecting workflow engines for microservices and distributed systems.
This blog post is a quick overview of why and how we did that.

After more than two years of development, we’re excited to announce the release of Zeebe 0.20.0. This is the first release where we’ve removed the “developer preview” label from Zeebe and are designating Zeebe as “production ready”. It’s a major milestone for the project.
In 2017, we created a dedicated team at Camunda with a vision to build a new workflow engine for high-performance applications running on modern, cloud-native software architectures. With Zeebe 0.20.0, we’ve taken a big step toward fulfilling that vision.
