The Serverless workflow specification relies on CloudEvents for event publishing and consumption. CloudEvents are designed in a way that might work with any event format. That goal is achieved by declaring the data property, the one containing the event information, as an array of bytes. Kogito Serveless workflow expects that incoming and outgoing events representRead more →
Expressions are an essential feature of Serveless Workflow Specification. They are everywhere and they are powerful. As you should already be aware if you have ever watched a superhero movie, with great power comes great responsibility. In the Kogito universe, when discussing expressions, this famous sentence means there is a risk you will overuse them.Read more →
As you probably know if you have read this previous entry, Kogito supports Serverless Workflow Specification. This allows you to write a Kogito process definition using a JSON or YAML file. Similar to a BPMN process, a Workflow can be understood as a state machine. In fact, a Workflow is defined by providing a setRead more →
This post illustrates the usage of Kogito add-ons which, during process execution, in an asynchronous way, are either publishing information to an external destination or waiting for a particular event to be triggered by an external source. This external actor will be in all cases configurable and typically, although not necessarily, will consist of anRead more →
At the beginning of the second decade of the twenty-first century we can still claim that smart humans are more clever than average machines. On the other hand, we probably have to admit that any machine is more reliable as a scheduler and reminder than an average human. So, when we face a task thatRead more →
In a previous post we discussed the task process API, which dealt with tasks from a process perspective. As explained in there, the task model depends on data defined by users. But, regardless of the task related information provided by users through BPMN processes, every existing task in Kogito has some predefined fields, mainly relatedRead more →
It can be argued that the greatest technical advances in the history of humankind (agriculture, wheel, steam machine, printing…) have augmented production while reducing human effort. This does not imply that these advances have removed human intervention altogether. On the contrary, they have allowed humans to focus on the most relevant parts of the productionRead more →
When I was studying my degree, I recall a wise teacher that repeatedly told us, their beloved pupils, that the most difficult part of a document is the beginning, and I can assure you, dear reader, that he was right, because I cannot figure out a better way to start my first entry on aRead more →
