由于高可用性的原因(核心组被视为高可用性域)，至少必须为每个访问点配置两个桥接接口。

Because of high availability (remember that a core group is considered as a high availability domain), a minimum of two bridge interfaces have to be defined per access point.

先读取(read - first)技巧涉及在尽可能高的应用层(通常为api层)对事务作用域范围外的读取操作进行分组。

The read-first technique involves grouping read operations outside of the transaction scope at the highest application layer possible (usually the API layer).
