Job Parameters

The Job Manager entities can be parameterized to be configured for an actual use case.

Entities that declare parameter variables are:

• Data object types
• Worker definitions

Entities that initialize or set parameters are:

• Job definitions
• Workflow definitions
  • Global workflow parameters
  • Local action parameters
• Bucket definitions

The parameter priority increases from top to bottom, meaning that the parameters in job definitions, for example, have a lower priority than those in workflow definitions.

Workflow definitions are special entities in as far as they allow you to define general parameters in the global workflow section and worker-specific parameters in local action sections. It is important to know that the latter do not affect the buckets that the respective worker is using. As a consequence, parameters declared in a data object type can only be initialized using global workflow parameters or job parameters alternatively.

Example

Job:

  {
    "name":"...",
    "workflow":"...",
    "parameters":{
      "p1":"a"
    }
  }

Workflow:

  {
    "name":"...",  
    "parameters":{
      "p1":"b"   // global workflow param, overwrites "a" from job def
    },
    ...
    "actions":[
       ...
      {
        "worker":"...",
        "parameters":{
          "p1":"c"  // lokal workflow param, overwrites "b" from global
        },
     ...
  }
