- - - - Incremental Id for each message
      - Unique for each partition
- - - - If message ordering is required
  - - - Wont wait for acknowledgement
      - Fast
      - Possible data loss
    - - Will wait for leader acknowledgement
      - Partial Data loss (Failer to reach partition replicas
    - - Leader + replicas acknowledgement
      - Slow
      - No data loss
- - - - At most once
        
        Committed as soon as the message is received
        
        Message would be lost if preprocessing goes wrong
      - At least once
        
        Committed after the message is processed
        
        Message can be read once if the process goes wrong. Make sure the system is idempotent
      - Exactly once
