Flowable[3] is an open-source workflow engine written in Java that can execute business processes described in BPMN 2.0.

Flowable is an actively maintained fork of Activiti (software).[4]

History

In October 2016, the lead developers of Activiti (software) left Alfresco (software) and started the Flowable Open Source project based on a fork of Activiti code.[5][6]

The first version of Flowable was 5.22, based on a fork of Activiti 5.21, but added Transient Variables.[7] The first release of Flowable version 6.0[8] was based on a fork of Activiti version 6 beta 4. Version 6 of the Flowable engine includes a rewrite of the core process virtual machine.

Components

The project comprises a set of modules that can operate together:

  • BPMN Engine, the core Business Process Model and Notation workflow processor
  • CMMN Engine, a Case Management Model and Notation processor
  • DMN Engine, an implementation of a subset of Decision Model and Notation based business rules
  • Forms Engine, a forms service that can be used in conjunction with the Tasks web app or a custom application
  • Modeler, a web-based graphical authoring interface for editing BPMN, DMN and forms models
  • Designer, an Eclipse plug-in for designing BPMN models
  • IDM, an example web tool to manage user and group identities and privileges
  • Tasks, an example web application to start processes, view task queues, tasks and forms

Differences between Version 5 and Version 6

The key changes in Flowable 6 are:[9][10]

  • Abstract persistence layer, enabling use of relational or non-relational data sources'[11]
  • 1-to-1 mapping of BPMN model to executable instruction set
  • Simplified execution tree, enabling easier analysis and manipulation of in-flight processes
  • Single agenda for process execution plans
  • Queue-based job execution[12]
  • Ad hoc Sub Processes[13]
  • Dynamic process execution[14]
