Mesos と Marathon は時々チェックポイントについて言及していますが、それがどのように機能するかについての適切な説明はどこにも見つかりませんでした。また、それは実際にはどういう意味ですか？
1) Is the Task current state continuously being stored, or is only the Task ID stored? Where is it stored and what does it contain?
2) There are two Marathon instances. Marathon has been running Nginx for a week, then goes down. Does that mean that the actual Nginx application state continues running on the second Marathon instance, or does it just restart the task from beginning? If the Task actual state is copied, isn't there a lot of data to be continuously persisted and passed around between slaves?
