MongoDB 中的节点与成员
Nodes vs Members in MongoDB
我对 MongoDB 文档中的术语感到困惑。在文档中它是混合的：有时 MongoDB 实例被命名为 node 有时 member。
见 https://docs.mongodb.org/manual/reference/replica-states/ 它说
... each member of a replica set has a state that reflects...
然后看到 https://docs.mongodb.org/manual/core/replica-set-primary/ 它说
In some circumstances, two nodes in a replica set may transiently
believe that they are the primary, but at most, one of them will be
able to complete writes with { w: "majority" } write concern. The node
that can complete { w: "majority" } writes is the current primary, and
the other node is a former primary that has not yet recognized its
demotion, typically due to a network partition
哪个在描述什么？
为什么文档使用 node 和 member 而不是其中之一？
有区别吗？
Member 和 Node 在 MongoDB 上下文中可以互换。两者都是有效和合法的。随心所欲。
