akka-stream提供了mapAsync+ask模式可以从一个运算中的数据流向外连接某个Actor来进行数据交换。这是一种akka-stream与Actor集成的应用。说到与Actor集成,联想到如果能把akka-stream中复杂又消耗资源的运算任务交付给Actor,那么我们就可以充分利用actor模式的routing,cluster,supervison等等特殊功能来实现分布式高效安全的运...

await foreach语句与foreach语句是一样的,只是它使用了IAsyncEnumerable代替Enumerable,在每次迭代都会去执行调用await MoveNextAsync(),并且这些枚举器的释放都是异步的。 同样,当你有可异步释放的对象时,你就可以通过using语句使用并异步的处理它:await using(var response = asyncDisposable){...}。await using跟 ...

另外,当使用长度为 0 的缓冲区调用Stream.Read或Stream.ReadAsync时,一旦使用非零缓冲区的调用成功,操作就会成功。 调用受影响的Read方法之一时,如果读取操作可以满足请求的至少一个字节,则无论请求了多少字节,它都会返回在那一时刻它可以返回的任意多的次数。
