Zeebe JobWorker binding spec

Detailed documentation on the Zeebe JobWorker binding component


To setup Zeebe JobWorker binding create a component of type bindings.zeebe.jobworker. See this guide on how to create and apply a binding configuration.

See this for Zeebe JobWorker documentation.

字段 必填 绑定支持 详情 Example
gatewayAddr Y 输入 Zeebe gateway address localhost:26500
gatewayKeepAlive N 输入 Sets how often keep alive messages should be sent to the gateway. Defaults to 45 seconds 45s
usePlainTextConnection N 输入 Whether to use a plain text connection or not true,false
caCertificatePath N 输入 The path to the CA cert /path/to/ca-cert
workerName N 输入 The name of the worker activating the jobs, mostly used for logging purposes products-worker
workerTimeout N 输入 A job returned after this call will not be activated by another call until the timeout has been reached; defaults to 5 minutes 5m
requestTimeout N 输入 The request will be completed when at least one job is activated or after the requestTimeout. If the requestTimeout = 0, a default timeout is used. If the requestTimeout < 0, long polling is disabled and the request is completed immediately, even when no job is activated. Defaults to 10 seconds 30s
jobType Y 输入 the job type, as defined in the BPMN process (e.g. <zeebe:taskDefinition type="fetch-products" />) fetch-products
maxJobsActive N 输入 Set the maximum number of jobs which will be activated for this worker at the same time. Defaults to 32 32
并发(Concurrency) N 输入 The maximum number of concurrent spawned goroutines to complete jobs. Defaults to 4 4
pollInterval N 输入 Set the maximal interval between polling for new jobs. Defaults to 100 milliseconds 100ms
pollThreshold N 输入 Set the threshold of buffered activated jobs before polling for new jobs, i.e. threshold * maxJobsActive. Defaults to 0.3 0.3
fetchVariables N 输入 A list of variables to fetch as the job variables; if empty, all visible variables at the time of activation for the scope of the job will be returned productId, productName, productKey


This component supports input binding interfaces.


The Zeebe workflow engine handles the workflow state as also workflow variables which can be passed on workflow instantiation or which can be updated or created during workflow execution. These variables can be passed to a registered job worker by defining the variable names as comma-separated list in the fetchVariables metadata field. The workflow engine will then pass these variables with its current values to the job worker implementation.

If the binding will register three variables productId, productName and productKey then the service will be called with the following JSON:

  "productId": "some-product-id",  
  "productName": "some-product-name",  
  "productKey": "some-product-key"
