Delete incomplete multipart uploads to Amazon S3 using an Amazon SDK

The following code example shows how to how to delete or stop incomplete Amazon S3 multipart uploads.

To stop multipart uploads that are in-progress or incomplete for any reason, you can get a list uploads and then delete them as shown in the following example.

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); } } }

To delete incomplete multipart uploads that were initiated before or after a date, you can selectively delete multipart uploads based on a point in time as shown in the following example.

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); } } } }

If you have access to the upload ID after you begin a multipart upload, you can delete the in-progress upload by using the ID.

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); } }

To consistently delete incomplete multipart uploads older that a certain number of days, set up a bucket lifecycle configuration for the bucket. The following example shows how to create a rule to delete incomplete uploads older than 7 days.

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()); } }
