I am running into a predicament when I use dataclasses for params. Sometimes, I want to pass in the entire dataclass into a task, other times I want to reference a specific field. I have explored two options: • Have a task that converts a dataclass to a named tuple • Use @dynamic workflows Using dynamic workflows works, but maybe there are side effects? I would love to learn from folks who have gone down this path before.

from flytekit import workflow, dynamic, task

@dataclass_json
@dataclass
class Params:
    color: str

@task
def print_color(c: str):
    print(c)
    
@dynamic
def wf(params: Params) -> Params:
    print_color(c=params.color)
    return inner

Cc @future-monitor-58430 I think Ankit and team offered to implement this in Flyte

For some context - this conversation. Basically, we could encode the Flyte

Literal

as a field of the dataclass rather than just the dataclass itself, then propeller internally can parse and retrieve the field when passing input values. I'm convinced it would be possible.

Oh nice! Looking forward to it 🙂.
