이 시나리오에서 내 문서를 어떻게 모델화해야하는지에 대한 귀하의 의견을 궁금하게 생각하십시오.큰 MultiMap + 숫자 줄이거 나 역 정규화
현재로서는 여러 다른 문서 모음에서 카운터/통계를 가져 오는 복잡한 MultiMap 색인이있는 것 같습니다. 내 dev 컴퓨터에서는 80ms 미만의 작은 크기의 테스트 데이터를 반환합니다 (이는 만족합니다.)).
내 프로덕션 서버로 갈 때의 성능은 평균적으로 매주 평균 약 500 회, 주당 200 회 다운로드, 좋아요, 즐겨 찾기 및 댓글이 수 차례 제공됩니다. 페이지 당 20-25 개의 믹스가 표시됩니다.
이 디자인을 유지 하시겠습니까, 아니면 내 카운터를 비정규 화하고 오디오 문서에 저장하는 것이 더 좋을까요? 인덱스는 성능이 좋으면 오히려 작을 것입니다.

대단히 감사합니다. Daniel. 패싯 접근 방식을 쓰기를 기대해보십시오 ... 그러나 주 카운터는 현재지도/축소 지수에서 제대로 작동하고 있습니다. 그러나 나는 귀하의 조언을 구할 것입니다. –
