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
• 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]
