Flowable Explained
Flowable is an open-source workflow engine written in Java that can execute business processes described in BPMN 2.0.[4] It is an actively maintained fork of Activiti (software).[5]
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.[6] [7]
The first version of Flowable was 5.22, based on a fork of Activiti 5.21, but added Transient Variables.[8] The first release of Flowable version 6.0[9] 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:
Differences between Version 5 and Version 6
The key changes in Flowable 6 are:[12] [13]
- Abstract persistence layer, enabling use of relational or non-relational data sources[14] [15]
- 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[16]
- Ad hoc Sub Processes[17]
- Dynamic process execution[18]
