Does an Append Upload Support the Lock Mechanism for Concurrent Operations?
OBS itself does not support this mechanism. If you want to prevent an object from being concurrently accessed, you must add a lock mechanism for objects in upper-layer applications.
If multiple clients simultaneously upload, query, or delete the same object or bucket, these operations may reach the system at different times and have different latency periods, so different results may return. For example, if multiple clients simultaneously upload the same object, the last upload request received by the system will replace the previous one.
