프로덕션 환경에 배포된 구조화된 스트리밍 작업이 하루 중 사용량이 많은 시간대에 지연 현상을 보이고 있습니다. 현재 정상적인 실행 시에는 각 마이크로배치 데이터 처리 시간이 3초 미만입니다. 하지만 사용량이 많은 시간대에는 각 마이크로배치의 처리 시간이 매우 불규칙해지며, 때로는 3초를 초과하기도 합니다.
30초. 스트리밍 쓰기는 현재 10초의 트리거 간격으로 구성되어 있습니다.
다른 모든 변수를 일정하게 유지하고 레코드를 10초 이내에 처리해야 한다고 가정할 때, 어떤 조정이 요구 사항을 충족할까요?

데이터 엔지니어 팀이 데이터 품질 검사에 대한 반복적인 요구 사항을 포함하는 테이블을 DLT 파이프라인에 추가하고 있습니다.
팀원 중 한 명이 이 파이프라인에 정의된 모든 테이블에서 이러한 데이터 품질 규칙을 재사용할 것을 제안했습니다.
그들이 이를 해낼 수 있도록 하는 접근 방식은 무엇일까요?

데이터 엔지니어가 Lakeflow Declarative Pipelines의 Expectations 기능을 사용하여 수신되는 센서 데이터의 품질을 추적하고 있습니다. 센서에서 주기적으로 범위를 벗어난 잘못된 측정값이 전송되는데, 현재는 해당 행에 경고 플래그를 지정하고 정상 데이터와 함께 실버 테이블에 기록하고 있습니다. 그런데 새로운 요구 사항이 생겼습니다. 잘못된 행을 별도의 격리 테이블에 저장하고 더 이상 실버 테이블에 포함시키지 않아야 한다는 것입니다.
이것은 그들의 은색 테이블에 대한 기존 코드입니다:
@dlt.table
@dlt.expect( " valid_sensor_reading " , " reading < 120 " )
def silver_sensor_readings():
return spark.readStream.table( " bronze_sensor_readings " )
What code will satisfy the requirements?

운영 환경에서는 외부 변경 데이터 캡처(CDC) 피드의 업데이트를 Delta Lake 테이블에 상시 실행되는 구조화된 스트림 작업으로 점진적으로 적용합니다. 이 테이블의 데이터를 처음 마이그레이션했을 때 최적화(OPTIMIZE) 작업이 실행되어 대부분의 데이터 파일 크기가 1GB로 조정되었습니다. 스트리밍 운영 작업에 대해 자동 최적화(Auto Optimize)와 자동 압축(Auto Compaction) 기능이 모두 활성화되어 있었습니다. 최근 데이터 파일을 검토한 결과, 대부분의 데이터 파일 크기가 64MB 미만인 것으로 나타났지만, 테이블의 각 파티션에는 최소 1GB의 데이터가 포함되어 있고 전체 테이블 크기는 10TB를 초과합니다.
다음 중 파일 크기가 작아진 이유를 가장 잘 설명하는 것은 무엇입니까?
Correct Answer: A 🗳️
