Zeebe vs kafka

Orchestration with Zeebe and Kafka as a workflow engine was approached to encounter the challenges faced by microservices.

The Kafka Producer and Kafka Consumer connectors are found here. This project uses Kafka Connect from Confluence. This Kafka Connect connector for Zeebe can do two things:. Send messages to a Kafka topic when a workflow instance reached a specific activity. Please note that a message is more precisely a kafka record , which is also often named event. This is a source in the Kafka Connect speak.

The Zeebe team just implemented a Kafka Connect Zeebe connector. Kafka Connect is the ecosystem of connectors into or out of Kafka. There are lots of existing connectors, e. Based on a POC, which I showed in a talk at Kafka Summit San Francisco recording available , the Zeebe team cleaned up the code which is pretty important if I wrote parts of it ;- and just released a version that is suitable for real-life usage. Send messages to a Kafka topic when a workflow instance reaches a specific activity. When I say message, I really refer to records in Kafka, where a lot of people also simply speak of events. This is a source in Kafka Connect speak. Consume messages from a Kafka topic and correlate them to a workflow. This is a Kafka Connect sink. A simple example to test if the connector is working for you is the ping-pong example on GitHub. It simply sends a message to Kafka which is directly correlated back. A common use case is around microservices orchestration. We have a simple example around the domain of order fulfillment in the microservices-orchestration example on GitHub. Another great example is around messaging integration patterns. For example we might want to wait for a couple of events to arrive before we want to trigger some activity.

From there another thread will actually take over and process the data. Jan Stenberg.

For example, at Kafka Summit New York City earlier this year, I was impressed how many big banks attended, that currently modernize their architecture.

This is known as projection. It receives data from the source system and makes it available to target systems in real-time. Click here. Or you could also sit back, relax, and watch this screencast:. The existing Zeebe Kafka Exporter might be exactly what you need — or a starting point to implement custom requirements. How we built a highly scalable distributed state machine. If you are familiar with the CAP theorem , it means that we decided for consistency and not for availability, so Zeebe is a CP system. Saga: How to implement complex business transactions without two phase commit. I will go over important concepts used in Zeebe and explain decisions we made on the way. You can get feedback on your model here, and rinse and repeat until you have a good grasp of what it could look like. Java has so called garbage collection which cannot be turned off. A simple example to test if the connector is working for you is the ping-pong example on GitHub. And then use remote debugging. Bernd Ruecker is co-founder and chief technologist of Camunda.

Especially if you do a small project or probably just start your journey into new architectures it might be much better to start small, which means not to include all the latest and greatest technology right away. Apart from scalability, Zeebe is also built for high performance on a single node from ground up. A projection in Zeebe is saved internally as a snapshot leveraging RocksDB , a very fast key-value store. You can create Kafka records whenever a workflow instance reaches a certain activity. Popular Searches Agile Digital Strategy. Well, we are migrating to microservices. While replication might add latency to the processing of a command within Zeebe, it does not affect throughput much. Fault tolerance: Zeebe is highly fault-tolerant, which means it can easily recover from machine or software failure with no data loss and minimal downtime. Recommended from Medium. Examples and walk-through. The Zeebe client and job workers can be configured by system properties understood by the Zeebe Java Client. Contributors Storing streams of record in a fault-tolerant way.
