8.4. Eventing system configuration precedence rules

The OpenShift Serverless Logic Operator follows a defined order of precedence to determine the eventing system configuration for a workflow.

Eventing system configuration precedence rules are as follows:

If the workflow has a defined eventing system by using either workflow-scoped outgoing or incoming eventing system configurations, the choice of configuration takes priority over the other configuration and applies to the workflow.
If the SonataFlowPlatform CR enclosing the workflow has a platform-scoped eventing system configured, this configuration is then applied to the next step.
If the current cluster is configured with a cluster-scoped eventing system, it is applied if no workflow-scoped or platform-scoped configuration exists.
Review the following information, if none of the above configurations are defined:
- The workflow uses direct HTTP calls to deliver SonataFlow system events to supporting services.
- The workflow consumes incoming events by HTTP POST calls at the workflow service root path /.
- No eventing system is configured to produce workflow business events. Any attempt to produce such events might result in a failure.
