JobRepository polymorphic dispatch — transient resource contention
What Happened#
2026-05-27 21:24:06 UTC에 us-west-2 리전의 cupixworks-api 서비스에서 Api::V1::JobsController#show 요청이 1015ms 소요되었다. 동일 시간대에 Job 1089729의 상태 전이(preprocessor running → complete)로 인한 대량 DB write가 발생하면서 데이터베이스 부하가 급증했고, 이후 21:29-21:33 UTC에 Elasticsearch 타임아웃으로 전체 API 티어에 걸친 cascading latency가 발생했다.
