task. However, I can provide you with a general idea of how to structure a flow with subflows.
Here's a simple example of a flow with subflows:
python
from prefect import Flow, Parameter
from prefect.tasks.s3 import S3Download
# Define the task
s3_download = S3Download()
# Define the subflows
with Flow("subflow-1") as subflow_1:
data = s3_download(bucket="my-bucket", key="path/to/data1")
with Flow("subflow-2") as subflow_2:
data = s3_download(bucket="my-bucket", key="path/to/data2")
# Define the main flow
with Flow("main-flow") as main_flow:
subflow_1_task = subflow_1()
subflow_2_task = subflow_2()
# Run the main flow
main_flow.run()
In this example, subflow-1
and subflow-2
are both subflows of the main flow. Each subflow downloads data from a different location in an S3 bucket. The main flow then runs these subflows.
Please note that this is a simplified example and does not include error handling or other complexities that might be present in a real-world scenario. Also, the s3_block.get_directory
task you mentioned doesn't seem to be a standard Prefect task. You might need to create a custom task for that.
