> In cloud environment, such as aws, aliyun etc., the internet delay is
> non-trival when we commit thounds of files.
> In our situation, the ping delay is about 0.03ms in IDC, but when move to
> Coud, the ping delay is about 3ms, which is roughly 100x slower. We found
> that, committing tens thounds of files will cost a few tens of minutes. The
> more files there are, the logger it takes.
> So we propose a new committer algorithm, which is a variant of committer
> algorithm version 1, called 3. In this new algorithm 3, in order to decrease
> the committer time, we use a thread pool to commit job's final output.
> Our test result in Cloud production shows that, the new algorithm 3 has
> decrease the committer time by serveral tens of times.
