The Boomerang Flow Workflow service provides the CRUD backing the front-end web tier, as well as the v1 APIs for direct consumption, and the executor for the workflow tasks.
Flow service provides APIs for:
- User & Team Management
- Creating / Updating workflows
- Executing workflows as Directed acyclic graph (DAG)
- Java 11
- Spring Boot 2.3
- Maven
If eventing is enabled on this service it will attempt to connect to, and subscribe to events. If you want to test this locally run:
docker run --detach --network host -p 4222:4222 --name nats-jetstream nats -jsVisit https://docs.nats.io/jetstream/getting_started/using_docker for more information.
The Java Quartz library is used for running scheduled jobs via mongoDB and underpins the Schedule trigger.
