기계 번역으로 제공되는 번역입니다. 제공된 번역과 원본 영어의 내용이 상충하는 경우에는 영어 버전이 우선합니다.

자바와 아마존 S3를 사용하여 대용량 Amazon SQS 메시지 관리

그러면 Java용 Amazon SQS 확장 클라이언트 라이브러리와 Amazon S3 (Amazon Simple Storage Service) 를 사용하여 대규모 Amazon Simple Queue Service (Amazon SQS) 메시지를 관리할 수 있습니다. 이는 256KB에서 최대 2GB에 이르는 대용량 메시지 페이로드를 소비할 때 특히 유용합니다. 라이브러리는 메시지 페이로드를 Amazon S3 버킷에 저장하고 저장된 Amazon S3 객체의 참조가 포함된 메시지를 Amazon Amazon SQS 대기열로 보냅니다.

Java용 Amazon SQS 확장 클라이언트 라이브러리를 사용하여 다음을 수행할 수 있습니다.

  • 메시지를 항상 Amazon S3에만 저장할지를 지정하거나, 메시지의 크기가 256KB를 초과할 때만 저장할지를 지정합니다.

  • S3 버킷에 저장된 단일 메시지 객체를 참조하는 메시지를 전송합니다.

  • S3 버킷에서 메시지 객체를 검색합니다.

  • S3 버킷에서 메시지 객체를 삭제합니다.

사전 조건

다음 예제에서는 AWS Java SDK를 사용합니다. SDK를 설치 및 설정하려면 AWS SDK for Java 개발자 안내서의 Java용 AWS SDK 설정을 참조하세요.

예제 코드를 실행하기 전에 AWS 자격 증명을 구성합니다. 자세한 내용은 AWS SDK for Java 개발자 안내서에서 개발을 위한 AWS 자격 증명 및 리전 설정을 참조하세요.

Java용 SDK 및 Java용 Amazon SQS 확장 클라이언트 라이브러리를 사용하려면 J2SE 개발 키트 8.0 이상이 필요합니다.

참고

Java용 Amazon SQS 확장 클라이언트 라이브러리를 사용하면 Amazon S3에 AWS SDK for Java만 사용하여 Amazon SQS 메시지를 관리할 수 있습니다. AWS CLI, Amazon SQS 콘솔, Amazon SQS HTTP API 또는 기타 AWS SDK에서는 이 작업을 수행할 수 없습니다.

다음 Java 2.x용 AWS SDK 예제는 임의의 이름으로 Amazon S3 버킷을 생성하고 14일 후에 객체를 영구적으로 삭제하는 수명 주기 규칙을 추가합니다. 또한 이름이 MyQueue인 대기열을 생성하고 S3 버킷에 저장된 256KB 이상의 무작위 메시지를 대기열로 보냅니다. 마지막으로 이 코드는 메시지를 검색하고, 메시지에 대한 정보를 반환한 후 메시지, 대기열 및 버킷을 삭제합니다.
