Sometime the broker writer failed to close, but we do not handle this failure. This may create an empty file on remote storage but be treated as normal. Also enhance some usabilities: 1. getting latest 2000 transactions instead of getting the earliest. 2. Show backend which download and upload tasks are being executed.
