Update features

Iterate on a Redis Feature Form definitions file with plan, merge, and re-apply workflows.

After the first ff apply, most changes will be iterative: edit the definitions file, preview the delta, apply, and verify. For the full apply mechanics and failure modes, see Define and deploy features.

Typical cycle

1. Change a resource definition.
2. Run a plan.
3. Apply the change.
4. Verify the resulting graph or catalog state.

Preview the change first:

ff apply \
  --workspace <workspace-id> \
  --file examples/featureform/docs/resources.py \
  --plan

Then apply:

ff apply \
  --workspace <workspace-id> \
  --file examples/featureform/docs/resources.py \
  --wait \
  --wait-for finished

When to use --merge

Use --merge when your file is intentionally partial and omitted resources should not be treated as deletions.

Verify the outcome

ff graph workspace stats --workspace <workspace-id>
ff catalog list --workspace <workspace-id>
