Writing a Zeebe Exporter – Part Two

In Part One, we built a minimal exporter, and learned about the exporter life-cycle methods. In this blog post, we will walk through building a Zeebe exporter for the Event Store database, an open source database for storing event streams. The complete source code for this example is available on GitHub. As well, there is a compiled version, along with a docker-compose configuration for it on the 0.18 branch of the zeebe-docker-compose repo. This exporter is based on the Simple Monitor exporter. The Simple Monitor exporter exports to an H2 database via JDBC. The exporter we are going to write uses REST to export to Event Store. We’ll use the same patterns for configuration, but we have less configuration, and…

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…
