triggered checkpoints, in
- **Trigger Time**: The time when the checkpoint was triggered at the
JobManager.
- **Latest Acknowledgement**: The time when the latest acknowledged 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 state size over all acknowledged subtasks.
+- **Checkpointed Data Size**: The checkpointed data size over all acknowledged
subtasks. This value would be the delta delta checkpointed data if incremental
checkpoint is on.
