分享一个老外写的相关文章 Serialization provides the ability to write a snapshot of a network of objects (the state of the application) to a byte stream, which may then be persisted to a file or database. Why not use serialization for the persistence layer? Unfortunately, a serialized network of interconnected objects can only be accessed as a whole; it’s impossible to retrieve any data from the stream without deserializing the entire stream. Thus, the resulting byte stream must be considered unsuitable for arbitrary search or aggregation of large datasets. It isn’t even possible to access or update a single object or subset of objects independently. Loading and overwriting an entire object network in each transaction is no option for systems designed to support high concurrency. Given current technology, serialization is inadequate as a persistence mechanism for high concurrency web and enterprise applications. It has a particular niche as a suitable persistence mechanism for desktop applications. --
