Writing a Zeebe Exporter – Part One

Exporters allow you to tap into the Zeebe event stream and export selected events to other systems. You can filter events, perform transformations, and even trigger side-effects from an exporter. In this post, we’ll step through implementing an exporter. In later posts, we’ll look more in depth at configuration and performance – but for now we’ll cover the bare minimum to help you understand how exporters work in Zeebe. Building an Exporter Follow along these steps to create a minimal exporter that can be deployed to a Zeebe broker. Note: Zeebe is under active development, and things may change. I have noted in each step things that are most likely to change. Create a new maven project: Add zeebe-exporter-api as…

Data Pipeline Orchestration With Zeebe (And An Example Map/Reduce Implementation)

Zeebe can be used to orchestrate data-processing pipelines, such as image processing or machine learning. As discussed in Google’s Site Reliability Engineering book, one issue with data-processing pipelines is responding in a timely fashion to increased business demands. Zeebe is a stateful workflow engine, and state doesn’t scale horizontally – but Zeebe does. So you want to design your pipelines in a way that encapsulates and isolates state and allows you to scale up workers in the parts where you can parallelize work. One computational solution pattern that enables this is Map/Reduce. In this post we’ll look at how you can use Zeebe to build Map/Reduce pipelines. This is not meant to be a production-ready solution, but just to get…

Class Not Found? There’s a simple solution

Generali Switzerland deployed Camunda BPM to production in less than six months, with no prior BPMN knowledge. You’ll find some more details about it in this case study. But integrating and deploying a new tool into your own technical environment is never entirely smooth sailing. In this blog post, we share how Generali’s engineering team was able to troubleshoot issues around running multiple workflow engines in their microservices architecture. You might also want to watch Generali’s presentation at CamundaCon 2018.

‘Introducing Operate’ Webinar Recording and Answers to Audience Questions

On April 24, 2019, we hosted our first-ever Operate webinar, sharing background on the problem that Operate seeks to solve and demoing a few of its core capabilities. A recording of the webinar has been uploaded, and you can find it here. We’d also like to put together answers to questions that came in during the webinar, including some that we didn’t have an opportunity to answer during the webinar itself.

How to run Camunda on Pivotal Cloud Foundry (PCF)

Camunda is a popular open source workflow engine that’s very lightweight and developer friendly. If you’re developing in Java you can use it embedded e.g. in Spring Boot applications. Otherwise you simply leverage its REST APIs and language clients, so Camunda can also be used in other programming languages. It can be integrated with basically every technology, including e.g. Kafka, RabbitMQ, REST or SOAP.

Zeebe and Fn Project Integrated: a Proof of Concept

Editor’s note: this post originally appeared on the Esentri blog. It was cross-posted here with Esentri’s permission. We’d like to give a shout-out to author Artun Subasi for his excellent blog post series on orchestrating serverless function with a workflow engine! I’d like to demonstrate a Proof of Concept (PoC) which integrates Zeebe with the Fn Project in order to orchestrate serverless functions using Business Process Model Notation (BPMN).
