How to disable automatic retries of failed Metaflow tasks?

Question

By default, MetaFlow retries failed steps multiple times before the pipeline errors out. However, this is undesired when I am CI testing my flows using pytest-- I just want the flows to fail fast. How do I temporarily disable retries (without hard-coding @retry(times=0) on all steps)?

Answer 1

You can disable it with by setting the METAFLOW_DECOSPECS environment variable: METAFLOW_DECOSPECS=retry:times=0.

This temporarily decorates all steps with @retry(times=0)-- unless they are already decorated, in which case this won't override the hard-coded retry settings.
