Spring Boot With Camunda Multi Tenant Support - Starter Project

Spring Boot and Camunda Multi-Tenant

This project represents starter project for multi-tenant mechanism in Camunda using embedded process engine.

Embedded process engine can be replicated but make sure that every engine points to the same database.

Setting project up

1. Create a database with name cam-multi-tenant
2. Run project

Artifact Deployment

There are two types of diagrams in this project. You have BPMNs that are common for all tenants, and for those diagrams there is auto-deployment setup. You can check parameters in application.yml file.

Tenant-specific diagrams are created in resources -> bpmn -> manual folder and you can deploy them using defined REST API service. You can find details bellow:

URL: http://localhost:8080/api/process-definition/{tenantId}/deploy
Content-Type: application/multi-part-form-data
Method: POST
Request payload: file=MultipartFile (BPMN or DMN file)

NOTE: Make sure you provide tenant identifier as path variable. Tenant id is unique identifier of tenant.

Testing

1. Enter to the Cockpit and pick up the process that you want to start
2. Check the token in running process instances

Multiple embedded engines environment

You can replicate this project and start both projects in parallel. Just make sure that both projects point to the same database. In this way, you can boost performance of Job Executor. Also, in this way you can achieve High Availability.
