개요

작업사항

  1. 영역 기반 교집합의 유무로 최적화를 진행합니다. ( 교집합이 없으면 만날 수 없음 )
    image.
  2. 교집합이 있을 경우 영역 Level 을 낮춥니다. ( 더 작은 영역으로 변환)
  3. 위 연산을 반복하면서 만남 조건을 충족하는지 검사하여 만난 사람에 대한 이벤트를 발행합니다.

영역 크기는 주석으로 작성해두었습니다. 아래 링크를 참고하세요
영역 크기 document 참고

변경로직

  • 만남 상수는 10미터로 설정해두었습니다.
  • 일부 Transactional 을 org.springframework.transaction.annotation.Transactional로 변환했습니다.

흠... 저라면 간단히
몽고디비에 사람 좌표 집어넣고

업데이트 된 좌표기준으로
10M 안에 있는 사람의 목록을 가져왔을것 같아요
넘 어렵게 가신거아닐까유!

아니면
geohash 사용해서

좌표 ->
wydm67k 변환
wydm67 까지 포함되는 좌표있는지 loop 한번만 돌고 끝내는 방법도 있을것같아요
참고요!
