Kotlin的流程控制
不同之处在于==还判断内部元素而===更多的是判断地址是否相同 看下面两个例子 val authors = setOf("Shakespeare", "Hemingway", "Twain") val writers = setOf("Twain", "Shakespeare", "Hemingway") println(authors == writers) // 1 println(authors === writers) // 2 上栗1的结果为true，2的结果为false，因为1是将内部数据排序然后比较数据，而2则是因为两个地址不同直接判断为false。 我们再看下里 val authors = setOf("Shakespeare", "Hemingway", "Twain") val writers = authors println(authors == writers) // 1 println(authors === writers) // 2 根据上面的原理俩个的结果可定都是true 最后就是 典型的三目？

ProxySQL 新版本对 MGR 的原生支持
For example in a 7 nodes clusters (Group of 7 members) where all nodes are writers (Multi-Primary mode ), it’s possible to decide to have only 2 writers, 3 readers and 2 backup-writers. This mean that ProxySQL will see all the nodes as possible writers but will only route writes on 2 nodes (add them in the writer hostgroup, because we decided to limit it to 2 writers for example), then it will add the others in the backup-writers group, this group defines the other writer candidates.
