Api::V1::AerialPhotosController#check_uploading (avg 1267ms, max 1434ms)

What Happened#

2026-05-27 09:14~09:15 UTC에 cupixworks-api 서비스의 AerialPhotosController#check_uploading 엔드포인트에서 평균 1267ms, 최대 1434ms의 응답 지연이 발생했다. 단일 사용자(Nestle 팀)가 CupixConnect 데스크탑 앱에서 Aerial Map 451에 대해 약 29개 aerial photo의 업로드 상태를 동시에 확인하면서, S3 API 호출과 DB 부하가 겹쳐 지연이 증폭되었다.
