Description
We suggest a new file naming for the completed metadata file:
${start_time}.${action}.${completion_time}
We also need a global Time Generator that can ensure the monotonical increasing generation of the timestamp, for example, maybe hold a mutex lock with the last generated timestamp backing up there. Say it may holds a lock L1. For each instant time generation, it needs guard from the lock.
Before creating the completed file, we also need a lock guard from L1.
Things need to note:
1. we only add completion timestamp to the completed metadata file;
2. we only add lock guard to the completed metadata file creation, not the whole commiting procedure;
3. for regular instant time generation, we also need a lock (that we should ship out by default)
