一 支持doubleBase 说明如下：

  1. gets
  • 1.1. master，失败就请求master_l1(目前不支持slave)；
  1. cas
  • 2.1. 首选master，unique id冲突，则返回失败；
  • 2.2. 其他情况，即认为成功（只要有一个layer可用，），改为set写所有layers。
  1. add
  • 3.1. 首先master回应失败，则认为失败；
  • 3.2. 其他场景，均认为成功（只要有一个layer可用）；
  1. set
  • 4.2. 不管master是否成功，统统set其他层；

二 备注

  1. 如果要避免set受master异常节点影响，设置force_write_all 为true即可
