You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: batch_average_counter.rb
    path of file: ./repos/gitlabhq/lib/gitlab/database
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  module Database
    class BatchAverageCounter
      COLUMN_FALLBACK = 0
      DEFAULT_BATCH_SIZE = 1_000
      FALLBACK = -1
      MAX_ALLOW
    
      def log_canceled_batch_fetch(batch_start, query, error)
        Gitlab::AppJsonLogger
          .error(
            event: 'batch_count',
            relation: relation.table_name,
            operation: 'average',
            start: batch_start,
            query: query,
            message: "Query has been canceled with message: #{error.message}"
          )
      end
