OutOfMemoryError uploading large file from API V2 - Java

[developersSave]

Hi everyone, 

I'm trying to upload a ".dump" file (size 3gb) from Java to my Dropbox application, but I've an error because the max size is 150mb.
I'm not finding any examples online, how can I fix that?

Following my code:

public static FileMetadata uploadDBDump(SuiteConfiguration suiteConfiguration, MultipartFile fileToUpload,
String pathFileName) throws UploadErrorException, DbxException, IOException {
DbxClientV2 dropboxClient = getV2ClientDBDumps(suiteConfiguration);
ListFolderResult folderList = dropboxClient.files().listFolder("");
String dropBoxFolderId = null;
for (Metadata metadata : folderList.getEntries()) {
if (StringUtils.equalsIgnoreCase("/" + pathFileName, metadata.getPathLower())) {
dropboxClient.files().deleteV2(metadata.getPathDisplay());
break;
}
}
CreateFolderResult createFolderV2 = dropboxClient.files().createFolderV2("/" + pathFileName);
dropBoxFolderId = createFolderV2.getMetadata().getId();

UploadBuilder fileUploader = dropboxClient.files()
.uploadBuilder(dropBoxFolderId + "/" + fileToUpload.getOriginalFilename());
fileUploader.withMode(WriteMode.ADD).withMute(Boolean.TRUE).withAutorename(Boolean.TRUE);
FileMetadata uploadMetadata = fileUploader.uploadAndFinish(fileToUpload.getInputStream());
return uploadMetadata;
}


Thank you!

To upload large files, you should use the "upload sessions" functionality instead. You can find an example of doing so with the Dropbox Java SDK here.
