The following discussion from !61471 (merged) should be addressed:

  I wonder, if this would not be helpful to also pass runner_ids, similarly to build_ids.

  This can be achieved by:

  unique_params = [
    :runner_type,
    :public_projects_minutes_cost_factor,
    :private_projects_minutes_cost_factor,
    :run_untagged,
    :access_level,
    Arel.sql("(#{arel_tag_names_array})")
  ]
  
  group(*unique_params).pluck('array_agg(id)', *unique_params).map do |values|
    Gitlab::Ci::Matching::RunnerMatcher.new(
      runner_ids: values[0],
      runner_type: values[1],
      public_projects_minutes_cost_factor: values[2],
      private_projects_minutes_cost_factor: values[3],
      run_untagged: values[4],
      access_level: values[5],
      tag_list: values[6]
    )
  end
