You can scale out individual Python functions to many containers using the .map() method.

You might use this for parallelizing computational-heavy tasks, such as batch inference or data processing jobs.

from beam import function


@function(cpu=0.1)
def square(i: int):
    return i**2


def main():
    numbers = list(range(10))
    squared = []

    # Run a remote container for every item in list
    for result in square.map(numbers):
        print(result)
        squared.append(result)


if __name__ == "__main__":
    main()

When we run this Python module, 10 containers will be spawned to run the workload:

$ python math-app.py
