排序连接以故障转移写副本

Question

I am using Sequelize 4.38.0. After reading the docs, I have setup a master write database with 2 read replicas. I am trying to add a fail over for the master write database for high availability. Does sequelize support this? Within the config options, in 'replications' you can pass an array of hosts to read, but not to write =\\

Answer 1

In Cloud SQL, the failover replica automatically replicates from the master and remains read only until a failover is needed. After a failover, the failover replica becomes the master and starts accepting writes. From the application's point of you, it's connecting to the same IP address.
