To improve security, the connection string is now stored encrypted and is decrypted only as needed; it can't be returned as plain text. The string can be obtained by using the CDatabase::Dump method. Signature of CWnd::OnPowerBroadcast is changed. The signature of this message handler is ...
线程池(Thread_pool)采用一定数量的工作线程来处理连接请求,通常比较适应于 OLTP 工作负载的场景。但线程池的不足在于当请求偏向于慢查询时,工作线程阻塞在高时延操作上,难以快速响应新的请求,导致系统吞吐量反而相较于传统 one-thread-per-connection(Per_thread)模式更低。 Per_thread 模式与 Thread_pool 模式各有...
