I have configured the server to use MySQL Cluster. The Cluster architecture is as follows:
One Cluster Manager(ip1)
Two Data Nodes (ip2,ip3)
Two SQL Nodes(ip4,ip5)
My Question: Which node should I use to connect from Python application?
You have to call SQL nodes from your application. Use comma separated ip addresses for this. In your code use DB_HOST = "ip4, ip5"
