I'm try to do an application using ruby sinatra + ruby sequel and it need
to *connecting multiple databases*. So how can i configure multiple
databases connection in ruby sequel or using master/slave concept?
*master/slave concept*
*DB=Sequel.connect('mysql2://master_server/database',
:servers=>{
:read_only=>proc{|db| {:host=>db.get_slave_host}},
:default=>proc{|db| {:host=>db.get_master_host}}
} )def
DB.get_slave_host @current_slave_host ||= -1
"slave_server#{(@current_slave_host+=1)%4}"enddef DB.get_master_host
@current_master_host ||= -1
"master_server#{(@current_master_host+=1)%4}"end*
