Camunda Engine Evolution since Activiti Fork

Written by Daniel Meyer on , under Execution category.

The future of the Activiti Open Source project is currently uncertain. Camunda split from the Activiti project in 2013. Since then, we maintained our own open source fork of the original Activiti Codebase.

The objective of this post is to illustrate the diverging directions the two projects have taken and to serve as input for users who now consider migrating from Activiti to Camunda. The first part focuses on two key topics: core BPMN Execution and the persistence layer. For me, after all the feature talk and the marketing-hurrah is said and done, BPMN and persistence is where the meat is. In the second part, I compare the current state of the Camunda codebase to the (unreleased) Activiti 6.

How to migrate from Activiti 5.21 to Camunda BPM 7.5

Written by Bernd Rücker on , under Execution category.

With the Activiti Core Developers having left Alfresco (the company behind Activiti), the future of the Activiti project is quite questionable. More and more Activiti users want to migrate to Camunda. There are actually very goood reasons to do so, see 5 Reasons to switch from Activiti to Camunda and Camunda Engine Evolution since Activiti Fork.

Camunda is a fork of Activiti. We actually developed big parts of the engine ourselves before we decided to part ways with Alfresco back in 2013. Hence it is relatively easy to migrate. This post lists the necessary steps to achieve this:

Efficient bundling of similar activities – Batch Processing with Camunda

Written by Luise Pufahl on , under Execution category.
Batch Processing in business processes is the ability to execute an activity or a set of activities for several business cases simultaneously. In practice, we can observe different cases where the bundled execution of several cases is beneficial and can improve process performance. In healthcare, it is more time-efficient to first collect a set of blood samples taken from patients to deliver them to the laboratory instead of sending a nurse for each separately.

Recommending CMMN Activities

Written by Thorben Lindhauer on , under Execution category.

The Case Management Model and Notation (CMMN) standard deals with unstructured work that is performed in the context of a so-called case. A CMMN model specifies the frame in which a case is handled. It expresses design time considerations, such as hard restrictions when an activity can be performed or not. Aside from that, there are often soft patterns that only emerge at runtime based on case workers’ experience. Detecting such patterns and providing insights to case workers can make dedicated case management with CMMN and Camunda especially useful.
