Hi, I have a technical question. Background of my question. I learned that in order to chain two tasks as dependent tasks, one task’s output must be the input of the other. I have a task that depends on a task (say to remove data in a folder) that doesn’t produce any output. How do I do it?

you could return a bool denoting if the task was successful or not then use

conditional

to execute the task if successful

Hi Augie, Thank you for your help. What if the previous task throws a runtime exception? The assumption in any workflow engine is if a previous task doesn’t error out, it’s considered successful and it will automatically trigger the next task. And this is such a common case. If I have to use a fake output as input, this place Flyte engine in the inferior class.

@Frank Shen, you can also chain flyte entities (docs: https://docs.flyte.org/projects/cookbook/en/latest/auto/core/control_flow/chain_entities.html#sphx-glr-auto-core-control-flow-chain-entities-py)

Thanks @Eduardo Apolinario (eapolinario), that helps a lot!
