name不是数据对象的唯一标识问题

[1076881851]

以name作为数据对象的唯一标识来存取数据，这种场景用户理解name是唯一标识，只存一份数据。但是当前以同一个name put两份数据，两份数据都会存进vineyard数据库里，元数据里的name是一样的；通过name取的是最新的一份数据，请问vineyard的设计是如何考虑的？老的数据是不是相当于残留了？

你可以通过object id拿到之前的数据，如果必须要用name对应一个object的时候，需要确保name不会被覆盖。另外你预期覆盖后是个什么行为比较好呢？

1. At present, when using the same name to write an object, the name will be associated with the latest written object, but existing objects will also retain that name Why not remove this name from existing external objects? What is the purpose of retaining this name on an existing object? Is it because of immutable data?

2. Can a user assume that they no longer need an existing object with the same name when writing a new object using that name? Can the existing object be automatically deleted, or can a prompt be returned to the user for decision? Or rather, due to immutable data, no deletion or other operations are performed; Only new objects can be added and associated with that name

@Daniel-blue Thanks for the detail. We can validate whether the name exists and make sure the object-name mapping not to be overwritten.
