Flowable
Flowable is an open-source workflow engine written in Java that can execute business processes described in BPMN 2.0.[3] It 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][12]
- 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[13]
- Ad hoc Sub Processes[14]
- Dynamic process execution[15]
