标题: c# - NHibernate读取交易

我已经阅读了有关为什么强烈建议在NH的读取操作中使用事务的文档和说明。但是,我还没有完全“购买”它。有人可以告诉我我已经做过的事,而不只是告诉我RTFM吗? ;)



Best Answer-推荐答案


This post from one of the authors可能有您的答案:

Even if we are only reading data, we want to use a transaction, because using a transaction ensure that we get a consistent result from the database. NHibernate assume that all access to the database is done under a transaction, and strongly discourage any use of the session without a transaction.

Leaving aside the safety issue of working with transactions, the assumption that transactions are costly and we need to optimize them is a false one. As already mentioned, databases are always running in transaction. And databases have been heavily optimized to work with transactions. The question is whatever this is per statement or per batch. There is some amount of work that need to be done to create and dispose a transaction, and having to do it per statement is actually more costly than doing it per batch.
