Multi-Language Workflows, Python and Go

This example demonstrates how to use the Tilebox SDKs to create a Workflows that uses tasks implemented in different languages, Python and Go. Go is used to submit the job, while Python is used to execute it.

Prerequisites

• Python 3.10+
• Go 1.24+
• Install the uv Python package manager – installation instructions
• Environment variables – provide your API key as environment variables
  • Tilebox API Key (TILEBOX_API_KEY) – create here

Getting Started

To start the runner, run the following commands:

cd python-runner

# Install dependencies
uv sync

# Start the runner
uv run runner.py

In a separate terminal, start the Go server:

cd go-server

go run .

Submit a job by calling the server's /submit endpoint:

curl http://localhost:8080/submit?lat=40.75&lon=-73.98&resolution=30&bands[]=489.0,560.6,666.5

The runner should execute the task and print the parameters to stdout.
