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
- Flowable Design, a cloud-based graphical authoring interface for editing BPMN, CMMN, and DMN [9][10]
Differences between Version 5 and Version 6
The key changes in Flowable 6 are:[11][12]
- Abstract persistence layer, enabling use of relational or non-relational data sources[13][14]
- 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[15]
- Ad hoc Sub Processes[16]
- Dynamic process execution[17]
