--------------------------------------
Summary: camel-aws2-s3 multipart upload multiplies file size by
number of parts
Key: CAMEL-15678
URL: https://issues.apache.org/jira/browse/CAMEL-15678
Project: Camel
Issue Type: Bug
Components: camel-aws2
Affects Versions: 3.5.0
Reporter: Kiril Nugmanov
Camel AWS2 S3 incorectly defines upload part content on multipart upload:
{{org.apache.camel.component.aws2.s3.AWS2S3Producer:193}}
{code:java}
for (int part = 1; filePosition < contentLength; part++) {
...
...
String etag = getEndpoint().getS3Client().uploadPart(uploadRequest,
RequestBody.fromFile(filePayload)).eTag();
...
}{code}
{{filePayload}} - is whole file to be uploaded.
In case when file size is bigger than {{partSize}} (which by default is 25MB) -
uploaded amount of content to S3 will be {{file.size * number_of_parts}}
Fix:
* define {{RequsetBody}} from stream:
{code:java}
InputStream inputStream = FileUtils.openInputStream(file);
IOUtils.skip(inputStream, filePosition);
completedParts.add(
CompletedPart.builder()
.partNumber(part)
.eTag(amazonS3Client.uploadPart(uploadRequest,
RequestBody.fromInputStream(inputStream, partSize)).eTag())
.build()
); {code}
