description	Rancang rollout fitur real-time secara bertahap dari sistem snapshot/polling ke event-driven dengan fallback aman. Gunakan saat perencanaan migrasi real-time end-to-end.

Realtime Rollout Planner

Kapan dipakai

• User meminta migrasi batch/pillar ke real-time.
• Ada kebutuhan menurunkan polling dan latency update.

Workflow

1. Definisikan event model dan sumber perubahan state.
2. Rancang outbox/event store + index query.
3. Tentukan strategi dual-write bertahap.
4. Tentukan consumer strategy (last_seen_id/cursor).
5. Tetapkan fallback ke snapshot path.
6. Definisikan observability (latency, drop, duplicate).

Format output wajib

• Arsitektur target (producer, event store, consumer).
• Rencana rollout fase A-E.
• Rollback/fallback.
• SLO metrik real-time yang harus dipantau.
