• Add replicas to dictionary replicaset
• Change function app.roles.api.get_employees_by_salary:

  local connection = assert(cartridge_rpc.get_connection('app.roles.dictionary', {leader_only = false}))
  local deps_data = connection:call('select', department_ids)
• (Optional) add ALL_RW to this replicaset or make space box.space.departments synchronious:

  box.space.departments:alter{is_sync = true}
