0 likes889 views
Flowable is an open-source project based on Apache 2 license, serving as a fork of Activiti with engines for BPMN, CMMN, and DMN. It focuses on achieving high performance, scalability, and easy integration into various technologies, with recent developments emphasizing a dynamic architecture and enhanced state change capabilities. The project has active community contributions and aims to provide a lightweight, embeddable framework for process management.

- 4. Some pretty graphs 4 Github Stars Forum
- 5. Some Interesting Numbers • In the last six months • 2 releases • 236 PR’s • 29 contributors 5
- 6. Some Nice Words • https://www.openhub.net/p/flowable 6
- 7. Our Goals • Performance • Scalability • Integrate easily into any project/any technology • Developer Power • Truly adaptive and dynamic • Build & deploy however you want 7
- 8. Flowable Engines in a nutshell Models Deployed - Standalone (e.g REST) - Embedded in any Java env (with mimimal resources needed) Engines APIs Apps Process (bpmn) Case (cmmn) Rules (dmn) - Web apps - Mobile - Machine to Machine - Open standards - Pluggability & extensibility Apps Process (bpmn) Case (cmmn) Rules (mn)

- 12. Performance & Scalability • https://blog.flowable.org/2018/03/05/flowable-6-3-0-performance-benchmark/ • https://blog.flowable.org/2018/03/13/async-history-performance-benchmark/ 12
- 13. Integration • Keep focus on being a lightweight embeddable framework • Spring Boot (talk later today) • Compatible release: 1 month after 2.0 release • On master: typically same day or max a few days • Spring 5 • JDK compatibility • Alternatives to relational db (MongoDB talk later today) 13
- 14. Async History
- 15. Truly Dynamic & Adaptive • State change logic • Adding/removing instances from multi-instance • Move from any state to any other state in a running process instance • Process Instance Migration (talk later today) • Both heavily using the v6 architecture changes 15
- 16. Refresher: V6 Architecture • Internal data structures are predictable • At any point during execution, we can calculate exactly the past and future state of the execution tree • Crucial for state change/migration in every situation • Optimizations beyond the v5 architecture • Behaviors are self-contained (no PVM/cleaner model) • Every new feature means more permutations. Less permutations means quicker new features & less bugs • More details in the “Process instance migration” talk later today 16
