Kế hoạch: Matching & Matchmaking Feature

1. Hiện trạng

  • MatchMatchingCmdConsumer: support cả prize_id và prize_ids (multi-match).
  • OpponentPoolCmdHandler: join/leave/query pool.
  • InvitationCmdConsumer: full invitation lifecycle.
  • Batch: MatchMakingForAllGameModeConfig scheduler, DeleteExpiredInvitationConfig cleanup.

2. Kế hoạch cải tiến

Phase 1: Validation & error standardization

  • Task 1-1: Chuẩn hóa error events cho matching/pool/invitation
  • Task 1-2: Test leave queue khi không có record (graceful)

Phase 2: Performance

  • Task 2-1: Tune matchmaking scheduler interval
  • Task 2-2: Monitor queue depth: prize-allocation và invitation queues
  • Task 2-3: Metrics: match success rate, average wait time

Phase 3: Testing

  • Task 3-1: Single prize flow end-to-end
  • Task 3-2: Multi-match prizeIds flow
  • Task 3-3: Invitation lifecycle test

3. Rủi ro

Rủi ro Ảnh hưởng Biện pháp
Inconsistent prizeIds không bị catch Sai queue routing Validate trước enqueue
Matchmaking scheduler overlap Double match fixedDelay thay vì fixedRate
Invitation TTL quá ngắn UX xấu Config TTL + monitor expiry rate
Leave graceful missing case User stuck Thêm test coverage
