RAILS MYSQL 查询优化（删除左连接以提高性能速度）

Question

我想优化这个 rails 查询

      teams
        .select("teams.*, COUNT(accounts.id) AS members_count_sql, SUM(accounts.points) AS total_points_sql")
        .left_joins(:team_memberships)
        .joins(
          ActiveRecord::Base.sanitize_sql(
            ["LEFT JOIN accounts on team_memberships.account_id = accounts.id AND accounts.id IN (?)",
             Account.visible_with_completed_profile.where(id:
              Licensing::Public::API.licensed_accounts_in_organisation(current_account.organisation.id)).pluck(:id)]
          )
        )
        .group(:id)
    end

并且teams_with_sortable_fields已从

    def index
      respond_ok(
        paginated_teams,
        each_serializer: V1::User::Management::TeamMetaSerializer,
        pagination: pagination(paginated_teams, PAGINATION_PER_PAGE),
        form: form_builder(object: team_search),
        sort_info: get_sort_info(permitted_sorts: PERMITTED_SORTS)
      )
    end

    def paginated_teams
      sorted_teams
        .page(params[:page])
        .per(PAGINATION_PER_PAGE)
    end
    memoize :paginated_teams

    def sorted_teams
      get_sorted_collection(
        collection: teams_with_sortable_fields,
        sort_spec: get_sort_spec(sort_mappings: SORT_MAPPINGS)
      )
    end

我试图优化这样的查询

    teams
        .select("teams.*, COUNT(accounts.id) AS members_count_sql, SUM(accounts.points) AS total_points_sql")
        .joins(team_memberships: :account)
        .merge(TeamMembership.where(
                 account_id: Licensing::Public::API.licensed_accounts_in_organisation(current_account.organisation.id)
               ))
        .group(:id)

但是这个记录不包括零账户的团队。 有没有其他我可以用相同的结果来固定这个查询，因为这会影响大量团队和客户记录的生产中的性能问题。
