I might be missing something, but is there a way to pass multiple arguments to a map task (ie. if I have a list

[1,2,3]

, can I pass each item to a map task along with some other fixed inputs that are common across all tasks). All the examples in the docs only include tasks w/ a single argument Relatedly, is there a way to use a workflow as part of a map task (ie. map a sub-workflow over a sequence of inputs) Edit: guess not

Map tasks only accept python function tasks with 0 or 1 inputs

@Rahul Mehta, dataclass/namedtuple is an acceptable way for now: https://docs.flyte.org/projects/cookbook/en/latest/auto/core/control_flow/map_task.html#map-a-task-with-multiple-inputs.

Ya this is actually a limitation of the flytekit api not the engine

@Ketan (kumare3) I can't find the issue, if you link it will upvote. Partial-like support would be very helpful

you are right, i did not find it too. I am not sure where it was lost. cc @Yee / @katrina do you know?

I would also be in favor of having the possibility to define default inputs to map tasks. Is there a plan of implementing this? A prepare_map_inputs task seems more like a workaround to me

It is you are right

Late, but finally filed a feature request here: https://github.com/flyteorg/flyte/issues/3120!
