Operations: Server: How to reoder database members?

ReorderDatabaseMembersOperation allows you to change the order of nodes in the Database Group Topology.

Syntax

public ReorderDatabaseMembersOperation(string database, List<string> order)

Example I

// Assume that the current order of database group nodes is : ["A", "B", "C"]

// Change the order of database group nodes to : ["C", "A", "B"]

store.Maintenance.Server.Send(new ReorderDatabaseMembersOperation("Northwind", 
    new List<string>
    {
        "C", "A", "B"
    }));

Example II

// Get the current DatabaseTopology from database record
var topology = store.Maintenance.Server.Send(new GetDatabaseRecordOperation("Northwind")).Topology;

// Reverse the order of database group nodes
topology.Members.Reverse();
store.Maintenance.Server.Send(new ReorderDatabaseMembersOperation("Northwind", topology.Members));
