다음을 사용하여 Amazon S3에 대한 불완전한 멀티파트 업로드를 삭제합니다. AWS SDK

어떤 이유로든 진행 중이거나 완료되지 않은 멀티파트 업로드를 중지하려면 다음 예와 같이 업로드 목록을 가져온 다음 삭제하면 됩니다.

    public static void abortIncompleteMultipartUploadsFromList() {
        ListMultipartUploadsRequest listMultipartUploadsRequest = ListMultipartUploadsRequest.builder()
                .bucket(bucketName)
                .build();

        ListMultipartUploadsResponse response = s3Client.listMultipartUploads(listMultipartUploadsRequest);
        List<MultipartUpload> uploads = response.uploads();

        AbortMultipartUploadRequest abortMultipartUploadRequest;
        for (MultipartUpload upload : uploads) {
            abortMultipartUploadRequest = AbortMultipartUploadRequest.builder()
                    .bucket(bucketName)
                    .key(upload.key())
                    .expectedBucketOwner(accountId)
                    .uploadId(upload.uploadId())
                    .build();

            AbortMultipartUploadResponse abortMultipartUploadResponse = s3Client.abortMultipartUpload(abortMultipartUploadRequest);
            if (abortMultipartUploadResponse.sdkHttpResponse().isSuccessful()) {
                logger.info("Upload ID [{}] to bucket [{}] successfully aborted.", upload.uploadId(), bucketName);
            }
        }
    }

특정 날짜 전 또는 후에 시작된 미완료 멀티파트 업로드를 삭제하려면 다음 예와 같이 특정 시점을 기준으로 멀티파트 업로드를 선택적으로 삭제할 수 있습니다.

    static void abortIncompleteMultipartUploadsOlderThan(Instant pointInTime) {
        ListMultipartUploadsRequest listMultipartUploadsRequest = ListMultipartUploadsRequest.builder()
                .bucket(bucketName)
                .build();

        ListMultipartUploadsResponse response = s3Client.listMultipartUploads(listMultipartUploadsRequest);
        List<MultipartUpload> uploads = response.uploads();

        AbortMultipartUploadRequest abortMultipartUploadRequest;
        for (MultipartUpload upload : uploads) {
            logger.info("Found multipartUpload with upload ID [{}], initiated [{}]", upload.uploadId(), upload.initiated());
            if (upload.initiated().isBefore(pointInTime)) {
                abortMultipartUploadRequest = AbortMultipartUploadRequest.builder()
                        .bucket(bucketName)
                        .key(upload.key())
                        .expectedBucketOwner(accountId)
                        .uploadId(upload.uploadId())
                        .build();

                AbortMultipartUploadResponse abortMultipartUploadResponse = s3Client.abortMultipartUpload(abortMultipartUploadRequest);
                if (abortMultipartUploadResponse.sdkHttpResponse().isSuccessful()) {
                    logger.info("Upload ID [{}] to bucket [{}] successfully aborted.", upload.uploadId(), bucketName);
                }
            }
        }
    }

멀티파트 업로드를 시작한 후 업로드 ID에 액세스할 수 있는 경우 ID를 사용하여 진행 중인 업로드를 삭제할 수 있습니다.

    static void abortMultipartUploadUsingUploadId() {
        String uploadId = startUploadReturningUploadId();
        AbortMultipartUploadResponse response = s3Client.abortMultipartUpload(b -> b
                .uploadId(uploadId)
                .bucket(bucketName)
                .key(key));

        if (response.sdkHttpResponse().isSuccessful()) {
            logger.info("Upload ID [{}] to bucket [{}] successfully aborted.", uploadId, bucketName);
        }
    }

특정 일수보다 오래된 미완료 멀티파트 업로드를 지속적으로 삭제하려면 버킷의 버킷 수명 주기 구성을 설정하세요. 다음 예시에서는 7일보다 오래된 미완료 업로드를 삭제하는 규칙을 생성하는 방법을 보여줍니다.

    static void abortMultipartUploadsUsingLifecycleConfig() {
        Collection<LifecycleRule> lifeCycleRules = List.of(LifecycleRule.builder()
                .abortIncompleteMultipartUpload(b -> b.
                        daysAfterInitiation(7))
                .status("Enabled")
                .filter(SdkBuilder::build) // Filter element is required.
                .build());

        // If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.
        PutBucketLifecycleConfigurationResponse response = s3Client.putBucketLifecycleConfiguration(b -> b
                .bucket(bucketName)
                .lifecycleConfiguration(b1 -> b1.rules(lifeCycleRules)));

        if (response.sdkHttpResponse().isSuccessful()) {
            logger.info("Rule to abort incomplete multipart uploads added to bucket.");
        } else {
            logger.error("Unsuccessfully applied rule. HTTP status code is [{}]", response.sdkHttpResponse().statusCode());
        }
    }
