CAS无锁算法 要实现无锁(lock-free)的非阻塞算法有多种实现方法,其中CAS(比较与交换,Compare and swap)是一种有名的无锁算法。CAS, CPU指令,在大多数处理器架构,包括IA32、Space中采用的都是CAS指令,CAS的语义是“我认为V的值应该为A,如果是,那么将V的值更新为B,否则不修改并告诉V的值实际为多少”,CAS是...
Eligible errors include only those made by a Live Bookkeeper. An “error” is: a) a transaction that has been incorrectly categorized to the wrong account; b) an account balance in QuickBooks that doesn’t match the actual account balance; or c) improper transactions which can’t be supporte...

You want your application to process messages as parallel long-running streams (messages are associated with a stream using the session ID property on the message). In this model, each node in the consuming application competes for streams, as opposed to messages. When a stream ...
