Java Batch upload via uploadSessionAppendV2
I am trying to batch upload multiple files via uploadSessionAppendV2, but somehow all the files are written to a single file.
Lets say i have two identical files file1.txt, file2.txt , each with si...
- It looks like you're only calling uploadSessionStart once. You'll need to call that once per file. That is, a single "upload session" is used to upload a single file. You can use uploadSessionFinishBatch to finish multiple different upload sessions at once though.
Cant figure it out how to delete the post, so i ll just post the answer about how to upload files in parallel.
UploadSessionCursor cursor = null;
for (int i = 1; i <= 100; i++) {
try {
file = localFiles.get(i);
remoteFileName = remoteFilePath + "/" + file.getName();
currentPath = file.getAbsolutePath();
try (InputStream in = new FileInputStream(currentPath)) {
sessionId = getCleint().files().uploadSessionStart(true).uploadAndFinish(in).getSessionId();
offset = file.length();
cursor = new UploadSessionCursor(sessionId, offset);
System.out.println("uploaded " + currentPath + " offset" + offset);
CommitInfo commitInfo = new CommitInfo(remoteFileName, WriteMode.OVERWRITE, false, new Date(), false);
UploadSessionFinishArg arg = new UploadSessionFinishArg(cursor, commitInfo);
entries.add(arg);
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
}
try {
System.out.println("Batch entries commit");
LaunchEmptyResult result = getCleint().files().uploadSessionFinishBatch(entries);
while (getCleint().files().uploadSessionFinishBatchCheck(result.getAsyncJobIdValue()).isInProgress()) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
UploadSessionFinishBatchJobStatus status = getCleint().files().uploadSessionFinishBatchCheck(result.getAsyncJobIdValue());
System.out.println(status.toString());
} catch (Exception e) {
e.printStackTrace();
}
