Example Workflow

An example of how to use Tilebox Workflows to implement a workflow in Go.

• submitter/main.go submits a workflow to Tilebox Workflows.
• runner/main.go starts a task runner.

Protobuf

This example uses a protobuf message to define SpawnWorkflowTreeTask task.

The task definition is defined in workflow.proto and the task implementation is in example_workflow.go.

The generated code of workflow.proto is in workflow.pb.go and can be (re-)generated using the following command:

go generate ./...

OpenTelemetry

This example uses OpenTelemetry to add tracing and logging.

To run the example, you need to set the additional following environment variables:

• AXIOM_API_KEYto your Axiom API key.
• AXIOM_TRACES_DATASET to the dataset where traces should be stored.
• AXIOM_LOGS_DATASET to the dataset where logs should be stored.
