Abstract

本发明实施例公开了一种数据读取方法、数据处理设备和***。所述方法包括：第一控制节点接收数据交换设备转发的读取消息，该读取消息用于指定读取第一数据，该读取消息由第二控制节点向该数据交换设备发送、再由该数据交换设备向节点组中除该第二控制节点以外的其它控制节点转发；如果第一存储节点中该第一数据的数据状态标识为有效标识，则该第一控制节点从该第一存储节点读取该第一数据，发送读取的该第一数据至该数据交换设备以使得该数据交换设备转发读取的该第一数据至该第二控制节点，该有效标识表明该第一存储节点上的该第一数据可用。本发明实施例保证节点组中控制节点之间通过消息交互来读取的第一数据是当前最新的。
