缠着我的头等待异步和NHibernate [英] Wrapping My Head Around await async and NHibernate

问题描述

给出以下代码:

private ISession _session;

public async Task<T> GetAsync<T>(int id) where T : ISomeEntity
{
    //how to call and return _session.Get<T>(id) asynchronous
}

是否可以异步调用NHibernate ISession.Get<T>()?建议吗?不值得吗?

Is it possible to call NHibernate ISession.Get<T>() asynchronously? Advisable? Not worth it?

推荐答案

在默认情况下，NHibernate在实体框架的意义上不支持异步等待.但是，建议这样做(如果可以的话)，因为数据库调用是IO调用，这是使其异步的很好的选择.结果，在等待来自数据库的响应时，您的线程将返回到池中而不是被挂起，这将使您的应用程序更具可伸缩性. 现在要异步支持.我已经分叉NHibernate实现了这一目标. 在我称为NHibernateX的fork中，有一些异步方法，例如GetAsync，ListAsync，ToListAsync等. 这是源代码和nuget软件包:

NHibernate does not support Async await in the sense of entity framework does by default. However it would be recommended to do so (if you could) since a database call is an IO call which is a very good candidate to make it async. As a result while waiting response from DB your thread will return to the pool instead of being pend and it will make your app more scalable. Now coming to async support. I have forked NHibernate to achive this. In my fork which I call NHibernateX, there are Async Methods like GetAsync, ListAsync, ToListAsync etc Here's the source and nuget package:
