Hi Prathap,
Suppose you have schema:
User extends V {
String number
String name
boolean registered
}
Users connected to friends with edges.
To get all registered users you can execute a following query
Select from User where regestered = true
To register new user check if vertex with the number already exists and
mark that vertex as registered by setting registered flag to true.
Best regards,
