How do you version features?

medium

Answer

$(1) Each feature has definition (name + computation code + owner + description).$
$(eg, \;\mathrm{user}_{7d}\mathrm{purchase}_{\mathrm{amount}}\mathrm{v2})$
$(3) Both versions computed in parallel during migration.$
$(4) Models declare which feature versions they consume.$
$(5) Deprecate old versions when no consumers.$
$Tools: Feast Registry, Tecton Feature Views.$
$Anti-pattern: silent feature computation change \to all downstream models silently regress.$

Check yourself — multiple choice

Random
Feature definition = name+code+owner+desc; version bumps on compute change; parallel computation during migration; models declare consumed versions; deprecate old
No versioning
Not real

Feature versioning: definition + version + parallel migration + deprecation.
