• Refactor
  • 턴/라운드 계산 로직 단순화로 진행 흐름이 더 예측 가능해졌습니다.
  • 선수 및 관련 정보 로딩 최적화로 봇 선택 시 지연이 줄었습니다.

Walkthrough

비동기 봇 턴 처리 로직이 DraftService에 추가되고, Redis 상태 키에 TTL(60분)이 TurnService에서 적용되었습니다. PlayerRepository에는 팀/포지션(ElementType)을 즉시 로딩하는 조회 메서드가 추가되었습니다. DraftService는 스케줄러로 봇 턴을 10초 후 실행하며, 트랜잭션 보장을 위해 self 프록시를 사용합니다.

Poem

깡총깡총, 열 번 세고 딱! 10초 뒤에 출발이야 🕒
토끼 봇이 줄을 서서 차례를 지켜봐요.
팀과 포지션 챙겨 들고, Redis에 소식 전하고,
바통은 둥글게 굴러가네—TTL로 따끈하게.
드래프트 밤하늘에, 별처럼 픽 픽 픽! ✨
