Resource recommendations

Baseline per-component resource requests for a standard self-hosted instance deployed with the official Helm chart:

Component	CPU	Memory	Ephemeral	Replicas
Backend	500m–1	1.5–4 Gi	1–2 Gi	2+
Scheduler worker	500m	1425 Mi	1 Gi	1
Warehouse NATS worker	250m	1.5 Gi	9 Gi	1
Pre-aggregate NATS worker	650m	4 Gi	9 Gi	1
Browserless	2	4 Gi	1 Gi	1
NATS	100m	256 Mi–1 Gi	—	1

NATS workers buffer large result sets on ephemeral disk before uploading to S3 — the 9 Gi ephemeral-storage request is not a typo.

Availability

Run at least two backend replicas with pod anti-affinity and a pod disruption budget:

replicaCount: 2

autoscaling:
  enabled: true
  minReplicas: 2
  maxReplicas: 10
  targetCPUUtilizationPercentage: 60   # backend only; workers scale via replicas

podAntiAffinity:
  enabled: true        # spreads each component across nodes (hard) and zones (soft)

podDisruptionBudget:
  enabled: true
  minAvailable: 1
