feat: Feature Server High-Availability on Kubernetes by ntkathole · Pull Request #6028 · feast-dev/feast

ntkathole · 2026-02-27T11:30:58Z

What this PR does / why we need it:

Add PodDisruptionBudget (PDB) support. PDB is only created when scaling is enabled and requires explicit user configuration (not auto-injected to avoid blocking node drains).
Add topology spread constraints with auto-injected soft zone spreading (ScheduleAnyway across topology.kubernetes.io/zone) when scaling is enabled. Users can override with explicit constraints or disable with an empty array.
Add pod anti-affinity with auto-injected soft node-level spreading (preferredDuringSchedulingIgnoredDuringExecution on kubernetes.io/hostname) when scaling is enabled. Users can override with explicit affinity configuration.
CEL validation enforces exactly one of minAvailable or maxUnavailable on PDB config.
