function to pause the flow after Task1 and then resume it using resume_flow_run
.
3. Implementation Steps:
- Task Definition:
python
from prefect import task, flow, pause_flow_run, resume_flow_run
@task(persist_result=True)
def task_one():
# Your task one code
return "some result"
@task
def task_two(input_data):
# Your task two code using input_data from task one
- Flow Definition:
python
@flow(persist_result=True)
def my_flow():
result1 = task_one.submit()
pause_flow_run(timeout=300) # Pause the flow for 5 minutes or specify the suitable timeout
result2 = task_two(result1.result())
To resume the flow:
python
from prefect import resume_flow_run
resume_flow_run(flow_run_id=<flow_run_id>)
For more details, here's the link to the relevant Prefect 3.0 documentation.
By doing this, you'll be able to ensure that restarting the flow by Task2 wouldn't need retrying Task1.Bring your towel and join one of the fastest growing data communities. Welcome to our second-generation open source orchestration platform, a completely rethought approach to dataflow automation.
