- **Latest Acknowledgement**: The time when the latest acknowledgement for any
subtask was received at the JobManager (or n/a if no acknowledgement received
yet).
- **End to End Duration**: The duration from the trigger timestamp until the
latest acknowledgement (or n/a if no acknowledgement received yet). This end to
end duration for a complete checkpoint is determined by the last subtask that
acknowledges the checkpoint. This time is usually larger than single subtasks
need to actually checkpoint the state.
- **Checkpointed Data Size**: The checkpointed data size over all acknowledged
subtasks. If incremental checkpointing is enabled this value is the
checkpointed data size delta.
-- **Processed in-flight data**: The approximate number of bytes processed
during the alignment (time between receiving the first and the last checkpoint
barrier) over all acknowledged subtasks.
-- **Persisted in-flight data**: The number of bytes persisted during the
alignment (time between receiving the first and the last checkpoint barrier)
over all acknowledged subtasks. This is > 0 only if the unaligned checkpoints
are enabled.
+- **Processed (persisted) in-flight data**: The approximate number of bytes
processed/persisted during the alignment (time between receiving the first and

could be larger than zero only if the unaligned checkpoints are enabled.
For subtasks there are a couple of more detailed stats available.
