Co-Browse - Redis - One Master Two Slaves Configuration
We are trying to add another redis slave to the existing configuration of a master and a slave in config.json. As the node js app's config is based on json it's accepting unique key value pairs only like
"redis" : {
"master" : {
"host" : " Proprietary information hidden"
},
"slave" :{
"host" : " Proprietary information hidden"
}
}
From the on-premise installation guide, its mentioned as one master and two slaves can be are configured. How can we add another slave to the existing configuration?

In the Co-Browse product config.json you can configure only one master and one slave. Co-Browse uses master for write operation and slaves for read operation wherever feasible. Co-Browse can connect maximum one slave only.
Above diagram shows example that you can configure application server to connect with any one slave.So that can be first or second and slave connection can be different for different application server.
At the infrastructure level you can have any no. of slaves. Those are for back up replica and failover scenario.
In case if you don't have slave then you can provide just master configuration and all operations will be performed on master.
To configure master and slave at infrastructure level please refer https://redis.io/topics/replication

Hi we are trying to configure Redis for both chat and co browse in the one master two slave configuration. Did you get it working in the end and if so what were the changes?

You can refer a master to multiple slaves in redis configuration file. Master points to Slave A and Slave A points to Slave B.
We went with one master - one slave configuration, as we thought this configuration is enough for the traffic we expect in real-time.
