hey guys! what is the similar to Airflow's '>>'? Example =

A >> [B, C]
[B, C] >> D
E

hi @Matheus Rocha - its my understanding that in airflow, the

>>

creates a state dependency between some tasks. In prefect, you can have either/both state dependencies or/and data dependencies. To create your example in prefect with only state dependencies

from prefect import flow, task

# implement tasks A-E, assume no data is passed between them

@flow
def my_flow():
   task_a_result = task_a()

   task_b_result = task_b(wait_for=[task_a_result])
   task_c_result = task_c(wait_for=[task_a_result])

   task_d_result = task_d(wait_for=[task_b_result, task_c_result])

   task_e(wait_for=[task_d_result])

or if hypothetically you wanted to pass data between these tasks

A >> [B, C]
[B, C] >> D

you could change that to create implicit data dependencies (and state! since the result is associated with the state)

# implement tasks A-E, assume B and C accept A's result as a kwarg, D accepts B and C's result as a kwarg
# more just like regular python
@flow
def my_flow():
   task_a_result = task_a()

   task_b_result = task_b(task_a_result)
   task_c_result = task_c(task_a_result)

   task_d_result = task_d(task_b_result, task_c_result)

   task_e(wait_for=[task_d_result]) # waits for D's result to materialize before running
