Here's a basic example:
from flytekit import task, workflow
from flytekit.sensor.file_sensor import FileSensor
# Define tasks
@task
def task_a():
print("Task A executed")
@task
def task_b():
print("Task B executed")
# Define the workflow
@workflow
def my_workflow(file_path: str):
sensor = FileSensor(name="test_file_sensor")
detected_file = sensor(path=file_path)
if "condition_a" in detected_file:
task_a()
else:
task_b()
if __name__ == "__main__":
my_workflow(file_path="s3://my-s3-bucket/file.txt")
In this example, the FileSensor detects a file, and based on the file's properties (e.g., its name or contents), it conditionally triggers either task_a or task_b.
Would you like more details on how to implement this or any specific part of the process?
